Please note these two user interface signs:
To create a new song press Song and choose New Song.
|•||= you can press and hold this for a second.|
|▼||= you can tap this.|
Before recording any tracks you may want to press Add Track and add a click track (metronome). If you want to see bars in track editors or you want to use score editors you'll have to record to a click track.
If you want to base your song on existing audio or MIDI files you can press Add Track and import the files. Files can be imported from AudioShare, the General Pasteboard or iTunes File Sharing. To use the latter option you'll have to put the files on iPad using iTunes (Mac or PC).Tap the Add Track button and add an audio or MIDI track. Then engage the track's Rec button and start the transport. Now you're recording.
AudioSlide over an audio track Rec button horizontally to select an input channel. A fader that controls the audio recording level is available (at the top) while a Rec button is engaged. If it's not present the sound device either has automatic gain control or there are hardware knobs to set the level. Make sure the track's level meter never goes in the red section.
Engage the Mon button if you want to hear the sound you're recording.
Tap the keyboard button in the bottom right corner and the built-in keyboard pops up.
If you want to record a USB MIDI keyboard you can connect it using a Camera Connection Kit or similar device. Tap the Studio button and select the right MIDI Input Device.
Tap the track's Instrument Slot (AKA. "the first effect slot") to change the sound. By default the MultitrackStudio Instruments are used. Press the slot for a second to pick a different MIDI instrument like the SoundFont Player or an IAA (Inter-App Audio) compatible app.
If you want to playback the MIDI track over USB press the MIDI track's Instrument Slot for a second and then pick "External". Also press the Studio button, choose Devices and make sure the right MIDI Out Device is selected. Enable 'Connect MIDI In and Out' if you're using separate master keyboard and synthesizer modules. Disable it if your keyboard has sounds of its own.
Tip: the existing part won't be removed if the SoS (Sound on Sound) button is engaged. This can be used for recording drum instruments one at a time etc.
Redoing a part1) If you made a mistake you can rewind to the start of the bad part and start recording from there. Make sure you stop the transport before recording over parts you want to keep.
2) More precise "punch ins" can be done using punch-in recording:
- Tap the track's name box to open the editor.
- Find the offending part.
- Switch the editor to Edit Mode (in the bottom left corner), and select the region you want to record.
- Make sure the Punch button is engaged.
- Move the transport position to a couple of seconds before the start of the punch-in region.
- Engage the track's Rec button and start the transport.
Tip: you can undo recording using the track editor's UNDO button.
3) Instead of redoing a part you can use the track editor to fix the problem.
PracticingYou can rehearse without recording if both a track's Play and Rec button are 'off'. If it's a MIDI track the track's instrument needs to be visible when transport starts. If it's an audio track one of the track's effects needs to be visible when transport starts, and the Mon button must be engaged.
Alternatively you can doubletap a track's Play button to switch it to practice mode manually. The Play button will read 'P', and the tracks stays in practice mode until you tap Play or Rec.An audio track's input channel selector features a 'Practice Mode tracks' option. Using this option you can record a track which is in 'manual practice mode' to an audio track. You can use this if you want to play an IAA app and record the app's output as audio, for example.
Setting this up goes like this:
- Doubletap a track's Play button to switch it to manual practice mode. The Play button now reads 'P'.
- If it's an audio track: engage the Mon button.
- Add an audio track, set its input to 'Practice Mode tracks' and engage its Rec button.
- Now you can hear it's working and you can start the transport.
Note: The Mon button has no effect on the audio track that's recording (you'd hear the practice mode track twice if it did).Tapping a track's name box opens its editor.
Editor modes It is important to understand the 'mode' buttons in the bottom left corner:
Audio editors have just one mode button: if it's engaged you can select parts and move them etc., if it's not engaged the editor is in 'pan mode' and you can swipe and pinch to move and zoom.
MIDI editors have three mode buttons: 'Select Part' works just like an audio editor, 'Select Notes' lets you select notes and move them. 'Add Notes' lets you add a note and switches back to 'Select Notes'. If no mode button is engaged the editor is in 'pan mode'.
The Automated Fader effect and MIDI controller editors have three mode buttons too: 'Select' lets you select and move dots, 'Add' lets you add dots while 'Draw' allows for free-hand drawing.
Tip: the mode buttons can be controlled by swiping horizontally over the left-hand part of the editor (the part above the mode buttons). This comes in handy for adding MIDI notes for example (swipe right, add note, swipe right, add another note etc.)
Scrolling and zoomingIf no mode button is engaged the editor is in 'pan mode' (see above). In pan mode you can swipe over the editor horizontally to scroll it. Pianoroll, Score and Drum editors can be scrolled vertically as well.
You can use two fingers to zoom horizontally. Audio, Pianoroll and Score editors can be zoomed vertically as well.
Additionally you can use the bottom bar to move (or zoom) the editors without switching to 'pan mode'. You can still use the corresponding area if an editor covers the bottom bar (the Song Editor does, for example). Similarly, the Pianoroll, Score and Drum editors can be scrolled (or zoomed) vertically using the editor's left-hand part - no need to switch to pan mode.
Tip: in 'select part' mode you can swipe down over the start or end of the selected part. The editor will zoom in until you release your finger again. You can use this feature to accurately set start/end points without having to actually zoom in and out again.
Audio editingThe audio editors feature DELETE, UNDO and REDO buttons. REPEAT can be used to repeat the selected part any number of times. The SEL button pops up a list of options including 'Select All' and 'Select Right'. The latter option selects the part from the current transport position to the end of the track.
The EDIT button pops up the Edit Control pane which allows for manipulating the selected part (Volume, Fade or Reverse).
The Pro Extension includes additional editing options:
- The edit control pane features a Transpose option. Preserve Formant can be enabled to make the transposed signal sound like the original (ie. to avoid the 'chipmunk' effect). Two algorithms are available: Polyphonic and Monophonic. If the audio track is monophonic you can switch to Monophonic which is faster and offers better sound quality.
- On tapping the SEL button you can enable the Stretch option. While this option is active resizing the selected part will change its duration accordingly. The Polyphonic/Monophonic setting mentioned above affects time stretching too.
MIDI editingMIDI tracks feature Pianoroll, Score and Drum editors. Use the PIANO/SCORE/DRUM tabs to pick one.
Like an audio editor, MIDI editors have UNDO, REDO, DELETE and SEL buttons. The Repeat option is available via the MORE button. The MORE button offers several more options:
- "Merge Paste" is like paste, but it doesn't remove existing notes.
- "Merge Notes" replaces the selected notes with a single note. The selected notes need to have the same pitch.
- "Split in equal parts" splits the selected note(s) in equal parts. You can use this to add triplets etc., or to quickly add a whole bunch of notes.
- "Expand to Chord" expands the selected note(s) to a chord. You can choose from over 20 chords.
The EDIT button pops up the Edit Control pane which allows for manipulating the selected part (Volume, Fade, Reverse, Transpose or Quantize).
The Score editor has a button that sets the duration of notes you add (it's on the left).
The Score editor's left-hand part can be tapped to get access to the Score Settings pane which offers Clef, Octave and Transposition settings. There's also a Key Signature setting, which can optionally be programmed to change at certain bars. The Key Signature settings affect all MIDI tracks.
The Drum editor features a horizontal strip called a Drum Instrument editor for each instrument used. The drum instrument's name is shown on the left hand side of the Drum Instrument editor. A different instrument can be selected upon double-tapping it. New instruments can be added by tapping Add Instr. Drum instruments can be reordered using drag-and-drop: drag a name box (on the left) horizontally until it starts moving first, then drag it up or down.
In Select Part mode you can select either a single instrument of all of them (move your finger diagonally to achieve the latter).
The CONTR button in the bottom right corner opens the MIDI Controller editor. You can pick a different controller after tapping the name of the current one on the left.
On 12.9 inch iPad Pro devices there's the Multi MIDI Editor (requires iPad Pro Pack). It allows for editing multiple MIDI tracks in a single editor, this makes arranging parts easier. To show the Multi MIDI Editor tap 'Edit' (at the top), then tap Multi MIDI Editor, and then pick one of the options. You can pick either all MIDI tracks of a particular color, all MIDI tracks with open editor or simply all MIDI tracks. The color options work best if you use different track colors for instrument groups like strings, woodwinds etc. To change a track's color longtap the track's name box.
The Multi MIDI Editor can show either a single pianoroll, a score editor with multiple staffs or a single drum editor. The pianoroll view features track buttons at the bottom. Newly added notes appear in the checked track. The MOVE button moves the selected notes to the checked track.
Moving audio/MIDI to other tracksThe selected part of a track can be copied to another track's editor using copy-and-paste or drag-and-drop. Note that you can even move data from MIDI tracks to audio tracks and vice versa, it will be converted automatically. Audio to MIDI conversion works with monophonic (ie. just one note sounds at a time) audio only.
If audio is drag-and-dropped from an audio track editor to a drum instrument editor only beats are detected (no pitch). You can, for example, tap a drum break on the table, record it as audio and move it to a drum editor.
Copying/pasting audio/MIDI to/from other appsThe COPY and PASTE buttons use a clipboard that's available to MultitrackStudio only. You can slide over these buttons horizontally to reveal a menu which offers options for copying to (or pasting from) the General Pasteboard or AudioShare. Copy copies the selected part only. Paste places the part at the current transport position (ie. the editor 'needle'). Audio tracks accept audio only. MIDI tracks accept both MIDI and audio. Only single-instrument MIDI data is supported (any additional instruments are ignored).
Changing the song structureThe Song Editor can be used to insert or remove parts of a song. It affects "everything": tracks, tempo and time signature, key signature (as seen in Score editors), markers and Automated Fader effects. Unlike track editors the Song Editor works in 'ripple mode', ie. the right-hand part shifts to the left if you remove a part etc.
Changing tempo / time signature
In the tempo editor you can select a part. Then you can move the tempo line up or down. Alternatively you can tap the EDIT button and type or tap a new tempo.
The Conduct feature lets you tap a new tempo. You can use this to create accelerandos etc. It works like this:
- Select a part in the tempo editor.
- Tap the CONDUCT button. The Conduct Tempo pane appears.
- Tap the rectangle to start. Transport starts at least one bar before the selected part automatically.
- Start tapping the beat on the rectangle.
- When the start of the selected part is reached the music will mute, and you can continue tapping the tempo for the selected part.
- When you've tapped enough beats transport will stop, and you can tap the OK button to close the Conduct Tempo pane.
If you've purchased the Pro Extension you can use the SEL menu's Stretch or Stretch Accelerando options, and then move the righthand side of the selected part. The accelerando version creates a gradual tempo change.
The tempo editor affects MIDI tracks only by default, so you'll typically want to get the tempo right before recording any audio. If you've purchased the Pro Extension there's an Audio check box on the right. Audio tracks are processed too if this box is checked. It's recommended to make sure any monophonic audio tracks use the monophonic transpose algorithm. Use their editor's EDIT button to access this option (a part needs to be selected for this button to be enabled).
In the time signature editor you can select bars, tap the EDIT button and choose a time signature. Note that editing the time signature does not affect the actual notes or controller values of MIDI tracks, use the Song Editor instead to achieve that.
Each track has a volume fader and a pan knob. An Automated Fader effect can be used in an effect slot if programming volume changes is required.
Audio tracks have 3 effect slots, MIDI tracks have 2 of them. A list of effects pops up after pressing a slot for a second. You can pick one or tap 'Empty' to remove the current effect from the slot.
Reverb is typically added to most if not all tracks. Inserting a Reverb effect in each track would require a lot of processing, that's why each track has an 'effect send' knob. This knob is labeled 'S'. There's also an Effect Return section which contains a Reverb effect already. Each 'S' knob controls the level sent to the Effect Return section, and hence the amount of reverb on that particular track.
If you've purchased the Pro Extension you can add either another Effect Return section or up to eight Group sections. Press Song and then choose Song Properties to access these options. Tracks feature an output selector box if any groups are present, so you can route the track's output to a group rather than the Master section. The outputs of the groups are routed to the Master section. You can use a group to apply a single compressor effect to multiple tracks, for example.
Tip: double tapping a Solo button invokes 'half solo', which dims the other tracks rather than mute them completely.A Master Limiter effect appears in the last effect slot automatically. This limiter keeps the signal below the highest possible level in order to avoid distortion.Settings up the Master Limiter is easy:
One would typically add a Compressor and an EQ in the other two slots. The compressor will have settings suitable for mastering automatically.Note that the Compressor and EQ affect the output level, so you'll have to check the Master Limiter setting again after making changes.
- Open the master limiter slot.
- Play back approx. 20 seconds of the loudest part of the song.
- Adjust the Drive knob so only a couple of low bars are covered. Don't cover high bars.
The EQ effect shows the Master output audio spectrum in a way that produces a straight horizontal line for a typical well-mastered recording. This serves as a guide for setting up the EQ.
Tip: cutting frequencies is better than boosting.Your work can be exported in several ways.
Export Mix: Exports the output of the Master section as a .wav audio file. The "Audio track quality" setting from the Preferences pane is used. The file can go to AudioShare, the General Pasteboard, Document Picker or the iTunes File Sharing folder. The Email option generates a .m4a file and attaches it to an email message.
Note: Any MIDI tracks using an External MIDI Instrument or Virtual MIDI App instrument should be recorded to audio tracks before exporting.
Tip: Export Mix produces a mono file if the Master section's Mono button is engaged.
Export MIDI Tracks: Merges MIDI tracks into a single MIDI file. The file can go to AudioShare, the General Pasteboard, Document Picker or the iTunes File Sharing folder. The email option attaches it to an email message. The MIDI file wil include the song's markers, if any.
Export tracks as audio files: Exports audio tracks and MIDI track using the MultitrackStudio Instruments as .wav audio files. You can choose the tracks. The file can go to AudioShare, the General Pasteboard, Document Picker or the iTunes File Sharing folder.
Export MultitrackStudio Song: Exports the song as a zip file. The file can go to Document Picker or the iTunes File Sharing folder. A zipped song can be opened in MultitrackStudio for iPad by tapping Song followed by Import Song. In MultitrackStudio for Mac or Windows it can be opened using the Song menu's 'Import Song...' option.
Files can be moved from the iTunes File Sharing folder to your Mac or PC using iTunes.
The Document Picker provides access to iCloud Drive. DropBox is available too if the DropBox app is installed.
Tip: Exported audio/MIDI files can be imported in a different song.In the top right corner of the screen are the start/stop button and the transport counter. The counter also serves for rewinding: swipe to the left to fully rewind, or swipe to the right to move to the most recent start position.
The overview bar, located right above the tracks, features the familiar 'moving thumb'. You can double tap the thumb to start transport (this also works with editor needle grips).
MarkersYou can add a marker at the current transport position by tapping the counter and choosing Add Marker. The marker appears on the overview bar. You can delete a marker by tapping it, then tap the counter and choose Delete Marker. Swipe down over a marker to reveal more options.
CyclingDouble tap-and-move the overview bar thumb to start cycling transport (don't lift the finger after the second tap but start moving it instead). The same trick can be done with an editor needle grip.
Alternatively you can tap the counter and use the Set Cycle Start/Set Cycle End options.
The overview bar shows the cycle region. You can cycle the current cycle region by longtapping the start/stop button.Each mixer section feature three effect slots (MIDI tracks have two slots). A list of effects pops up after pressing a slot for a second. The following effects are available:
Auto Wah (requires Pro Extension)The Auto Wah is a resonant low pass filter.Its cut off frequency goes up if the signal level goes up and vice versa.
The Frequency knob sets the lower limit for the filter frequency. Range sets the difference between the highest and lowest filter frequency. Sensitivity determines how much the filter frequency changes in response to a certain input level. The Attack and Release knobs determine how fast the filter frequency responds to level changes.
Automated FaderThe Automated Fader is a volume control that can be programmed to change over time. It can be used to attenuate, amplify or mute part of a track. The fader will move in a linear fashion from one dot to another. Dots can be added, removed or moved using the editor.
ChorusThe Chorus effect adds thickness and warmth to the signal. The output signal is a mix of the input signal and a delayed copy of it. The delay time is modulated.
The Delay knob sets the average delay time. The Speed and Depth knobs control the modulation. The Mix knob sets the dry/wet ratio (0% being dry only, 100% being wet only). If the Stereo button is active a stereo chorus effect will be applied to mono signals (this is usually the effect you're looking for).
CompressorThe Compressor attenuates loud parts, while leaving soft parts untouched. Apart from this, it can make sounds 'fatter' or just make them fit better in the mix without any significant compression taking place.
The Threshold knob controls the level above which compression takes place. The Attack knob controls how fast the Compressor will attenuate loud signals, while the Release knob controls the time it takes to stop attenuating after a loud signal ended. Low Release times can cause distortion at low frequencies. The Gain knob sets the amount of gain applied after the compressing action is done. As the Compressor attenuates loud parts the overall level drops. The Gain knob compensates for this level drop. By activating the Auto Gain button the Compressor will automatically adjust the Gain knob.
The Transfer Curve (bottom left) shows the effect of the Threshold, Ratio and Knee settings. It ignores the effect of the Gain knob. The horizontal axis represents the input, the vertical axis represents the output. The Level History (top left) shows the relative amount of time the input signal is at a certain level (the higher the bar, the more time).The Convolutor effect processes the audio signal using an impulse response. It comes with 4 plate reverb, 2 spring reverb and 2 digital reverb impulse responses. You can import your own impulse response files as well.
Tip: you can swipe over the Impulse Response box vertically to step through the impulse responses.
The Volume knob controls the output level. The 'Mix with input' button adds the dry input signal to the output of the effect. The Delay knob adds a delay to the processed signal. This can be useful for reverb applications. The Random button applies subtle modulation which makes reverbs sound smoother. You can switch this off if you're using non-reverb IRs like guitar speakers or mics.
DeEsserThe Deesser effect reduces 'S' sounds in vocals in a very unobtrusive manner. The De-Es knob controls the amount of attenuation applied to 'S' sounds. Applying too much attenuation will result in unnatural sounding vocals. The Threshold knob controls the level above which the Deesser becomes active. The Range knob controls the dynamic range the Deesser operates on. The threshold can be made to float within a certain range, so low-level parts can also be effectively deessed. The Frequency knob controls the frequency above which 'S' sounds are detected. If this control is set too low the Deesser will be too sensitive (i.e., sounds that are not a 'S' will be attenuated). By engaging the Monitor Button you can hear the filtered signal the Deesser uses. You can uses this option to judge whether the Frequency knob is set up correctly (ideally you only hear 'S' sounds and nothing else).
Dynamics (requires Pro Extension)The Dynamics effect combines a Limiter, a Compressor and an Expander in one effect. The Expander part can be used to attenuate background noise for example.
The Dynamics effect supports sidechaining. The Sidechain box allows for selecting another track as sidechain source, so 'ducking' etc. are possible. You can use the Monitor button to listen to the sidechain signal.
The Attack knob controls how fast the Compressor and Limiter will attenuate loud signals, while the Release knob controls the time it takes to stop attenuating after a loud signal ended. Low Release times can cause distortion at low frequencies. The Gain knob sets the amount of gain applied after dynamics processing has been done. The Limiter Threshold knob controls the level above which the limiting action takes place.
The Transfer Curve on the left shows the effect of the current settings of the Limiter Treshold knob, the Compressor/Expander Treshold, Ratio and Max.Att. (maximum attenuation) knobs and the Gain knob. The horizontal axis represents the input, the vertical axis represents the output. The vertical Gain Reduction meter shows the current amount of gain applied by the effect. The Level History (top left) shows the relative amount of time the input signal is at a certain level (the higher the bar, the more time).
EchoThe Echo effect produces one or more echoes, depending on the Feedback knob. If the Feedback knob is at zero position only one echo is produced. Otherwise a decaying sequence of echoes is produced.
The Delay knob controls the time it takes for the first echo to arrive (and the time between two consecutive echoes). The delay time is displayed in milliseconds and notes.The Lo-cut knob sets the frequency below which attenuation takes place (this typically happens in tape echo units).The Hi-cut knob sets the frequency above which attenuation takes place (this also happens in nature and in tape echo units).The TapeSound knob controls the amount of flutter and distortion.The Mix knob controls the level of the echoes that are mixed with the dry (input) signal (0% is dry only, 100% is echo only).
EQThe EQ effect consists of six tone control sections. The overall transfer is showed in the display at the top. Each section has its own Bypass button.
The Lo Cut section is a lo cut filter. The cut off rate can be 6, 12 or 18 dB/octave. The cut-off frequency can be 20 Hz up to 2 kHz.
The Bass section can be a shelving or a one-octave bell-type equalizer. Boost/Attenuation can be -12 dB to +12 dB. Frequency can be 20 Hz to 1 kHz.
The Lo Mid section is a parametric equalizer. The center frequency can be 50 Hz up to 2 kHz. The Bandwidth can be 0.05 to 2 octaves. The Gain can be -12 dB to +12 dB.
The Hi Mid section is a parametric equalizer. The center frequency can be 500 Hz up to 12 kHz. The Bandwidth can be 0.05 to 2 octaves. The Gain can be -12 dB to +12 dB.
The Treble section can be a shelving or a one-octave bell-type equalizer. Boost/Attenuation can be -12 dB to +12 dB. Frequency can be 1 kHz to 20 kHz.
The Hi Cut section is a hi cut filter. The cut off rate can be 6, 12 or 18 dB/octave. The cut-off frequency can be 500 Hz up to 20 kHz.
FlangerFlanging is the effect that occurs when two tape recorders playing back the same signal run slightly out of sync.
The Delay knob sets the average delay time. The Speed and Depth knobs control the modulation. The higher the Feedback knob position, the more effective the effect is. If the Stereo button is engaged the delay times of both stereo channels will be modulated with out-of-phase signals.
Guitar AmpThe Guitar Amp effect emulates three vintage guitar amps: Combo USA, Combo UK and Stack. It emulates the amp, its speaker and the microphone recording it. In addition up to three stompbox effects can be used.
The Level knob controls the level of the guitar signal presented to the amp. The three lights located next to the knob serve as level indicator. They can be used to make the amp see the same input level a hardware amp would. The SC (single coil) light will light if the level equals the output of a single coil pickup. The HB (humbucker) light will light if the level equals the level of a humbucker pickup. The Hot light will light if the level is even higher.
Three stompbox effects can be inserted between the guitar and the amp. Auto Wah, Booster, Chorus, Compressor, Delay, Echo, Flanger, Noise Gate, Phaser, Pickup EQ, Reverb and Tremolo are available. Each effect features two knobs.
The Booster stompbox is a treble booster. A huge number of classic rock sounds were created using a device like this.
The Pickup EQ stompbox can be used to change the characteristics of the guitar pickup. You can turn its Treble knob down to compensate for a shrill sound caused by a very short guitar cable, or to make a single coil pickup sound more like a humbucker. Turning Treble up can make a humbucker sound more like a single coil pickup.
Three amp models are available: Combo US, Combo UK and Stack.
The Combo US model features Volume, Treble, Mid and Bass knobs and a Bright switch. The Bright switch has no effect if the Volume knob is all the way up.
The Combo UK model features two channels. The Brilliant channel features Volume, Treble, Bass and Cut. The Cut knob attenuates high frequencies. The Normal channels features Volume, Bass and Cut knobs. The Bass knob cuts a certain amount of bass, closely emulating the the bass response of various versions of this particular amp.
The Stack model features Volume, Treble, Mid and Bass knobs. In addition there are Bottom, Hot and Gain buttons. These buttons change certain components of the amp, and hence change the sound. All variations correspond to versions of the hardware amp being modeled.
The Cntr/Edge knob controls the position of the recording microphone. 0% is at the center of the guitar cab's speaker, 100% is at the edge. The knob offers 7 positions. The Output knob controls the output level. The horizontal meter shows the output level. It is important to stay out of the red section if the amp is played live, in order to avoid clipping. Typical values range from 0 dB (overdrive sounds) to approx. 10 dB (clean sounds).
If you've purchased the Pro Extension there's a box below the Cntr/Edge knob which allows for loading your own speaker impulse response file. The Cntr/Edge is not available in this case.
Note: the impulse responses are shared with the Convolutor effect.
Master LimiterThe Master Limiter can be used to maximize the level of the mix. It's supposed to be used in the last (right hand) effect slot of the Master section.
The level is limited just below the digital full scale level (-0.3 dB). This small margin serves to avoid distortion in samplerate converters, CD players, soundcards etc.
The RMS Output meter indicates the perceived loudness. A pop song's chorus typically reads approx. -17 dB, that's why this level is marked by a triangle. Classical music typically reads approx. -23 dB during forte parts.
Note: the -17 dB and -23 dB levels correspond to the 0 dB levels of the K-14 and K-20 metering systems respectively.
The Peak Statistics display shows the relative amount of time the input signal is at a certain level (the higher the bar, the more time). This gives you an idea as to what the limiter is doing to the audio signal. There's a colored 'curtain' on the right side of the display that can be moved using the Drive knob. The vertical bars that are covered by the curtain are limited. You'd typically want to limit a couple of small bars only.
Multiband Compressor (requires Pro Extension)The Multiband Compressor splits the audio signal in three frequency bands, and applies compression to each band. It is typically used in the Master section when a single band compressor can't provide the level of compression required without side effects like a loud kick drum noticeable muting high frequency parts.
The Bass/Mid and Mid/Treb knobs set the frequency band crossover points.
The three compressors have six knobs each: Threshold controls the level above which compression takes place. Gain sets the amount of gain applied after the compressing action is done. As the compressor attenuates loud parts the overall level drops. The Gain control compensates for this level drop. Ratio and Knee control the shape of the compression curve. Attack controls how fast the compressor will attenuate loud signals, while Release controls the time it takes to stop attenuating after a loud signal ended. Low Release times can cause distortion at low frequencies. Low Ratio settings and relatively low Treshold settings are typically used for mastering purposes.
The display shows the average gain (including the Gain knobs) as a solid line. If you want to apply compression without changing the frequency spectrum significantly you can use the Gain knobs to make each band's average gain approximately 0 dB. The bars at the top of the display represent the peak reduction (not including the Gain knobs).
Noise GateThe Noise Gate attenuates signals below a certain level. It can be used to remove noise from a track.
The Threshold knob determines the level below which the signal is attenuated. The Reduction knob controls the amount of attenuation applied to signals below the threshold. Applying lots of attenuation can make a Noise Gate slow. The Attack knob controls the time it takes for the Noise Gate to open (ie. let the signal through). The Release knob controls the time it takes for the Noise Gate to close (ie. attenuate the signal). The Hold knob sets an absolute time to wait after the signal drops below the threshold. The release phase starts when the Hold time has elapsed. The Open indicator lights when the gate is open.
The Level History on the left shows the relative amount of time the input signal is at a certain level (the higher the bar, the more time). Also, the current input level is shown horizontally at the bottom. This Level History makes it very easy to set up the threshold. There's a colored 'curtain' on the left side of the display that can be moved using the Threshold knob. The signal bars that are covered by the curtain are muted (the gate is closed).
Phase Inverter (requires Pro Extension)The Phase Inverter inverts the phase of the signal, just like a mixing desk's polarity switch.
PhaserThe Phaser effect has a selectable number of Notches (frequency regions that are attenuated) that can be moved through the frequency spectrum slowly. Traditional stomp-box type of phaser used with electric guitars typically have two notches, expensive studio devices have a higher number of notches. The Frequency knob controls the tonal character of the effect. The Range knob determines the distance the notches move. High values can lead to noticeable pitch shifts. The Speed knob controls the speed used to move the notches. The Depth knob controls how deep the notches are (the deeper the notches, the more intense the effect). The Stereo button can be used to create a stereo effect by moving the left and right channel notches in opposite directions.
ReverbThe Reverb effect offers four programs. 'Room' is a small room program, can be used to add 'ambience' to vocals. 'Chamber' is an echo chamber program. 'Hall' is a concert hall program. 'Plate' is plate program. The Reverb effect is typically used in the Effect Return section.
The Pre Delay knob controls the time it takes for the first reflection to appear. The Rvrb Time knob controls the reverb time. The Mix knob mixes the wet (ie. reverb) and the dry (ie. input) signal. 0 % is dry only, 100% is wet only. Lo Mult is a multiplier for the low frequency reverb time, while Lo Freq sets the frequency below which Lo Mult is active. Hi Cut sets the frequency above which the reverb time is decreased gradually. If Spin is not zero some of the reverb algorithm's parameters are modulated with a low frequency signal. This makes the reverb more random and smoother. Too much Spin will introduce noticeable pitch shifts in the reverb (easily noticeable on piano parts). Percussion parts may benefit from a higher Spin setting. Width controls the stereo width of the reverb.
RotorThe Rotor effect simulates a rotating speaker. It consists of bass and treble speakers rotating independently. The speakers are driven by a tube amplifier and two microphones are used to pick up the sound.
The Amplifier section contains the Drive control that controls the level the 'tube amplifier' is operating on. This can be used to add tube distortion. The Rotors sections controls the speaker's rotation speed. Tremolo is fast, Chorale is slow. The Mics section controls the microphone placement used to record the speaker cabinet. Distance controls the distance between the mics and the cabinet. Spread controls the stereo channel separation. Balance controls the relative levels of the treble and the bass speakers. The cabinet is miked with two microphones at a 180 degree angle. This angle can be reduced to 90 degrees using the Narrow Angle button.
SaturatorThe Saturator effect adds either Tube or Tape type distortion, depending on the Tube and Tape buttons. The Drive knob controls the amount of distortion.
The Tube program simulates a preamp with an output transformer. The preamp mainly generates second order harmonics, the transformer generates lower order odd harmonics. The Tube program adds harmonics, not unlike an exciter effect. The Drive knob controls the signal level that's fed to the virtual preamp's input. The VU meter shows the average value. At 0 dB total harmonic distortion is approx. 2%.
The Tape program models distortion, high frequency compression, low frequency peaks and wow & flutter. It can be used on individual tracks to make them sound a bit warmer. The Tape program can also be used on a full mix (ie. in the Master section). This makes the tracks blend better. The Drive knob Drive controls the virtual recording level. The VU meter shows the average value of the recording level. At 0 dB VU total harmonic distortion is approx. 1%. The LF Peak knob controls low frequency peaks ("bumps"). The Flutter knob controls the amount of wow & flutter.
Stereo ImagerThe Stereo Imager effect can change the width the the stereo image. It works with both stereo and mono input signals. The Width knob controls the stereo image width. The Reverse button reverses the left and right channels.
Mono input signals are converted to stereo using a filter. Shelve and Comb filter types are available. The Shelve option directs low frequencies to the left channel and high frequencies to the right channel. The Color knob controls the crossover-frequency. The Comb filter adds a delayed signal to the left channel and subtracts it from the right channel. The Color knob controls the distance between the notches of the comb filter.
The Stereo Imager is mono compatible: if the stereo outputs are summed the resulting signal is equal to the original mono input signal.
Transposer (requires Pro Extension)The Transposer effect shifts the pitch of the audio signal by the amount set by the Semitones and Cents knobs. Pitch can be shifted up to one octave up or down. The Transposer features two programs: Monophonic and Polyphonic.
The Monophonic program is optimized for monophonic ("one note at a time") audio. It features a Formant knob which shifts the formant of the sound. Pitch shifting sounds most natural if the formant is shifted in the other direction (ie. if pitch is shifted up 2 semitones the formant should go down two semitones).
The Polyphonic program is optimized for polyphonic audio. It is extremely CPU efficient while still producing good sounds. Part of the efficiency comes from a limited headroom, which is where the Level knob comes in. If the light above it lights up the audio signal is clipped and you should turn the Level knob down a bit. This typically won't happen, but it may if the signal has been amplified by other effects. If a track has been recorded at a very low level you can turn up the Level knob to maximize sound quality.
The Transposer doesn't work in a track that's recording.
TremoloTremolo modulates the level of the signal with a sine wave. The Speed and Depth knobs control modulation speed and depth. The Stereo button can be used to create a stereo effect by modulating the right channel with a phase shifted version of the sine wave.
TunerThe Tuner effect can be used to tune instruments like guitar, bass etc. It typically works best if it's used before any other effects (like the Guitar Amp).
VibratoVibrato modulates the pitch of the signal with a sine wave. The Speed and Depth knobs control modulation speed and depth. The Stereo button can be used to create a stereo effect by modulating the right channel with a phase shifted version of the sine wave.
Vocal Tuner (requires Pro Extension)The Vocal Tuner can be used to correct out-of-tune vocals. It features two programs: Natural, which corrects pitch in a very unobtrusive manner, and Modern, which sounds a bit synthetic and robot-like.
The Natural program's Speed knob sets the speed at which pitch is corrected. A slow setting leaves note onsets and vibrato intact.
The Modern program features more knobs. The Correction knob sets the amount by which out-of-tune notes are corrected. At 100% pitch is perfect, which usually sounds rather synthetic. Lower settings allow for more natural sounds. The ignore section contains knobs that make the tuner ignore certain parts of the sound in order to avoid unwanted artifacts. Ambient ignores background noise during silent parts. Sibilant ignores unpitched sounds like "s". Note that the Vocal Tuner doesn't do anything if you turn an "ignore" knob up by too much.
The key editor shows both the input pitch (dimmed color) and the output pitch (bright color). The Vocal Tuner quantizes pitch to the closest key. Using the key editor you can turn keys off for certain parts. If a key is off pitch is quantized to the closest key which is on. The Vocal Tuner doesn't do anything if all keys are off. The key editor looks like a one-octave pianoroll. You can select part of a horizontal bar that represents a key, and use the ON or OFF buttons to switch the selected part on or off. Selecting multiple adjacent keys is possible as well.
The Vocal Tuner is a mono effect, you can use it on a stereo track but the signal will be converted to mono. The Vocal Tuner doesn't work in a track that's recording.
AU PluginsAudio Units, introduced in iOS 9, can be used in an effect slot just like a MultitrackStudio effect.
IAA Effect AppsIAA effect apps can be used in an effect slot just like a MultitrackStudio effect. There can be only one instance of a particular app, and MultitrackStudio doesn't store or recall the app settings. Both are limitations of IAA.
For more information see the Audio Units, Inter-App Audio and Audiobus chapter.The left-hand slot of a MIDI track is an instrument slot rather than an effect slot. A list of instruments pops up after pressing an instrument slot for a second. The following instruments are available:
MultitrackStudio InstrumentsThe MultitrackStudio Instruments are a General MIDI compatible instrument collection. It contains over 100 instruments including a drum kit.
Use the box in the top left corner to pick an instrument. The instruments appear in five categories: Keyboard, String, Wind, Percussion and Synth. The large box in the middle contains knobs, drawbars or buttons which control the sound of the selected instrument. Not all instruments offer controls.
Tip: you can swipe over the instrument box vertically to step through the instruments.
Keyboard instruments: Acoustic and electric piano's feature a Strength knob which controls how hard the piano is played. It adds a value to a note's velocity. '2.5' is neutral position. The electric piano's Dynamics knob controls the velocity curve, ie. it controls how sensitive the piano is to key pressure. Bass and Treble are tone controls, as found on amplifiers or even some electric pianos. The Percussive Organ is percussive even if another note is playing. This is different from the Wheel Organ which follows the traditional style. Drawbar Organ / Percussive Organ rotor speed can be controlled using MIDI controller #1 (Modulation).\
String instruments: Bass guitars feature a Strength knob which controls how hard the bass is played. It adds a value to a note's velocity. '5' is neutral position. Violin Section, Violin Section 2, Viola Section, Cello Section and Contrabass Section are specialized versions of String Ensemble 1. There are two violin sections in order to lessen phasing problem with unison notes. Bowed strings feature a Vibrato knob similar to the winds (see below).
Wind instruments: Most wind instruments feature a Vibrato knob. Vibrato is applied automatically depending on the musical context (especially note duration). The knob controls the amount of vibrato. You can avoid vibrato on certain notes by programming MIDI controller #1. The value at approx. 300 ms after the note onset is the value that counts. It's not possible to add vibrato where the automatic system thinks it's not appropriate.
Percussion instrument: The Drum Kit uses MIDI channel 10 in order to be compatible with General MIDI. A suitable channel is picked automatically when you load an instrument, so you typically don't need to pay attention to the Channel box.
Synthesizers: Almost all synth sounds use the same synthesizer which comes in three versions: square, sawtooth and triangle. The bottom-right corner of the Controls box shows the version. The sawtooth version is used for most sounds. The four drawbars control the level of four oscillators. 8' is the root note. 8'D is a slightly detuned version. 5'1/3 is a fifth and 4' is one octave up. The Attack, Decay, Sustain and Release knobs represent a classic ADSR envelope. If Sustain is higher than "5" the level will rise during the decay phase. The pad sounds use this swelling effect.
Some instruments, like Harp and Drum Kit, ignore note-off events. A sustain-off event will mute all sounding notes for which a note-off event has been received, so you can use the sustain pedal to mute harp strings or cymbals etc.
SoundFont PlayerThe SoundFont Player can load .sf2 files. Many .sf2 files are available on the internet. Use the SoundFont box to load one of the available .sf2 files. The Import option allows for importing additional ones.
Use the Preset box to pick one of the presets provided by the current SoundFont. You can swipe over the preset box vertically to step through the presets quickly.
Matrix SamplerThe Matrix Sampler can load up to 16 audio samples. They can be played using the Matrix onscreen keyboard for example.
A 4x4 matrix of cells appears on the left. On tapping one of the 16 cells the corresponding controls appear on the right. The Load button allows for loading samples. Several options are available:
In addition you can copy from one cell to another using drag-and-drop. Samples can be up to 6 seconds in length. If you have longer samples you can consider slicing them into parts using a track editor, the parts can then be loaded in multiple cells using the paste option.
- Import an audio file from AudioShare, the General Pasteboard or iTunes File Sharing.
- Paste data copied from audio or MIDI track editor.
The text box next to the load button shows the name of the cell, and allows for changing it. The name appears in the cell itself if a sample is loaded.
Volume controls the volume of the sample. Semitones and Cents control the pitch. Stretch can be used to make the sample shorter or longer, so it matches the song tempo. The box accepts fractions, so you can type '120/80' instead of '1.5' to make a 120 BPM sample match your 80 BPM song for example. If Oneshot is engaged the sample will play all the way to the end regardless of note-off messages.
You can use the play button to playback the sample. This can come in handy while copying data from a tracks to cells, when there's not enough room for the matrix keyboard.
The Matrix Sampler supports the following MIDI messages:
- Note On/Off
- Volume (cont. 7)
- Expression (cont. 11)
The cells are mapped to MIDI notes 36..51.
External MIDI InstrumentAn External MIDI Instrument sends the track's MIDI data to a MIDI Out device. This will typically be a MIDI device connected via USB.
To select the MIDI Out Device press the Studio button, choose Devices and make sure the right MIDI Out Device is selected. Enable 'Connect MIDI In and Out' if you're using separate master keyboard and synthesizer modules. Disable it if your keyboard has sounds of its own.
The Patch section determines which patch is used. You can use the Select button to select a patch by name. The Bank:prog box allows for entering bank and program numbers. The bank and program numbers (0..16383 and 0..127 respectively) are separated by a ':' character (for example: 1:2 means Bank 1 and Program 2).
The Controls section offers quick access to often used MIDI controllers. You can use the track's MIDI controller editor if you need more options.
The small button below the patch name box can be used to select a patchmap different from the default one specified in the Preferences pane. A patchmap contains the names corresponding to the bank:program numbers. You can create you own patchmap files and move it to iPad using iTunes. The MultitrackStudio patchmap file specification is available at http://www.multitrackstudio.com/patchmaps.php.
AUi PluginsAudio Units, introduced in iOS 9, can be used in an instrument slot just like a MultitrackStudio instrument.
IAA Instrument AppsIAA instrument apps can be used in an instrument slot just like a MultitrackStudio instrument. There can be only one instance of a particular app, and MultitrackStudio doesn't store or recall the app settings. Both are limitations of IAA.
An app's onscreen keyboard can be recorded if you make the app send its MIDI output to the 'MTS IAA Recording' destination. Note that all data sent to 'MTS IAA Recording' gets recorded, even if it's sent by another app. Some apps may forward incoming MIDI messages to 'MTS IAA Recording'. You may have to make such apps stop using 'MTS IAA Recording' in order to avoid recording tracks that are playing back.
For more information see the Audio Units, Inter-App Audio and Audiobus chapter.
Virtual MIDI AppsA Virtual MIDI App instrument sends the track's MIDI data to an instrument app via MIDI. All running apps which support this appear in the instrument selector.
Note: you need to launch the app yourself to make it appear in the instrument selector.
The MIDI Input Device you've selected in the Devices pane has to be selected as input in the app too if you want to record it.
An app's onscreen keyboard can be recorded if you make the app send its MIDI output to the 'MTS Virtual MIDI Recording' destination. Note that all data sent to 'MTS Virtual MIDI Recording' gets recorded, even if it's sent by another app. Some apps may forward incoming MIDI messages to 'MTS Virtual MIDI Recording'. You may have to make such apps stop using 'MTS Virtual MIDI Recording' in order to avoid recording tracks that are playing back.
You can use Audiobus to make switching between apps and controlling the transport easier.
Up to four instrument apps can be used simultaneously. Multiple tracks can use the same app (you can route 16 tracks to an app for example, each track using a different MIDI channel).
Note: the track's volume fader, pan knob and mute/solo buttons won't work if the app doesn't respond to standard volume/pan MIDI messages.
Tip: switch off iPad four/five-finger multitasking gestures in order to avoid moving to another app accidentally.
The onscreen MIDI Keyboard can be used to play the instruments. The button in the bottom right corner of the screen makes the keyboard visible. The slider on the left controls volume (MIDI controller 7). It can be assigned to any other controller (including note velocity and pitch) using the Options button.
Several layouts are available via the Options button:
KeyboardThe keyboard layout is a piano keyboard. The bar at the top can be used to move the keys horizontally. It also allows for making the keys wider or narrower using two fingers. Finger Vibrato can be enabled via the Options button. Only monophonic parts can be played while it's enabled.
ChordsThe Chords layout allows for playing chords with a single finger. It offers 12 keys for major chords and 12 keys for minor chords. You can use the 6/7/Maj7 buttons on the left to add a note to the chord. The narrow vertical slider sets "the position of the keyboard player's hand on the keyboard".
Guitar, Bass, Cello, Viola and ViolinThe string layouts offer horizontal strings with frets. You can play a note by pressing a string (place your finger between two frets). String layouts can be capoed using the Options button. Finger Vibrato and/or String Bend can be enabled via the Options button. Only monophonic parts can be played while Finger Vibrato and/or String Bend are enabled.
DrumThe drum layout uses GM instrument mapping. You can close the hihat pedal movements by moving your finger: first put a finger on the HH Open pad to 'hit it with a stick', then move the finger to the HH Close pad to close it with the pedal.
The pads sound a bit louder in the top-right corner. The Bass, Snare and Side pads sound a bit louder in the top-left corner because they are typically played using the left hand.
MatrixThe Matrix layout can be used with the Matrix Sampler. The pad mapping conforms to the Matrix Sampler's matrix mapping. The 8 pads on the left correspond to the lower 8 cells of the Matrix Sampler, the 8 pads on the right correspond to the upper 8 cells.The mixer sections and audio effects can be automated (ie. the knobs can be programmed to turn automatically while the transport is running). This can be used to change a track's pan position dynamically or to add more reverb to part of a track etc.
All automation movements have to be programmed using a control's Automation Editor, which works just like an Automated Fader effect. It's not possible to record fader or knob movements directly. A control's Automation Editor can be made visible using the Automation button in the bottom right corner of the screen. First, tap the Automation button, so it turns white. 'A' labels will appear on all automatable controls while the Automation button is engaged. Tap one to pop up its automation editor.
A small blue square appears in the bottom right corner of an automated control. In case of AU plugins it appears next to the Bypass button or Channel selector. Automation can be undone by deleting all dots in the editor.
'Delay' knobs may cause glitches while turning. It's best the move these knobs in a quiet part.There are three ways to use other apps with MultitrackStudio.
iOS 9 introduces Audio Unit effects and MIDI instruments. This is the preferred way to integrate 3rd party apps in MultitrackStudio.
Apps that aren't available as Audio Unit can be used via Inter-App Audio or Audiobus.
Use Inter-App Audio if you want to record MIDI or the unprocessed audio signal. After recording the track the app is still used to playback the recording.
Use Audiobus if you want to record the app's audio output. Once recording is done the app is no longer needed.
Audio UnitsAudio Units integrate in MultitrackStudio just like AU or VST plugins do under OS X or Windows. They basically behave similar to built-in MultitrackStudio effect/instruments.
Inter-App AudioApps which support Inter-App Audio (IAA) can be loaded in an effect or instrument slot:
- The app's Rec button toggles the Rec button of the track it's in. You need to press the play button to actually start the transport.
If you're recording the IAA app using the 'Practice Mode tracks' option the recording track's Rec button will be used instead. This only works if there's exactly one audio track which uses the 'Practice Mode tracks' input.
- The app's rewind/play/rec buttons don't work if you left MultitrackStudio by pressing iPad's home button. You need to tap an effect/instrument slot instead to switch to an IAA app.
- Some apps don't work correctly if the app wasn't running already before loading it in MultitrackStudio. In particular, playback can be silent. Make sure these apps are running before you load them in MultitrackStudio.
- 'Generator' apps (apps having no MIDI or audio inputs) can be used in a MIDI track's Instrument Slot. The app obviously won't respond to any notes appearing in the track editor etc. Apps that don't need user interaction will work right away (eg. a drummer app which drums along with the tempo set by MultitrackStudio). Other apps can be recorded to an audio track using the 'Practice Mode tracks' input option.
- Do not use MIDI Clock to sync the app with MultitrackStudio. The IAA protocol provides means for syncing in a far more reliable way. If an IAA app needs MIDI Clock please ask the developer to support syncing via IAA.
- MultitrackStudio doesn't store/recall the app's settings. iOS currently doesn't allow for that.
- There can be only one instance of a particular app, that's an iOS limitation. You'll have to remove the existing instance in order to be able to add a new one. After pressing an audio track's name box you can choose 'Apply effects', this will apply the effects to the track and remove them from the effect slots. MIDI tracks have a 'Copy to new audio track' option, this creates a new audio track containing an audio version of the MIDI track.
- Instrument apps: while an app is loaded there's no way to change the MIDI channel MultitrackStudio uses for this app. It's recommended to switch your apps to 'omni' mode (if available), so it responds to all MIDI channels. Otherwise you need to make sure the current instrument uses the right MIDI channel before loading the app. If need be you can temporarily load the MultitrackStudio Instruments to change the channel.
- An instrument app's onscreen keyboard can be recorded if you make the app send its MIDI output to the 'MTS IAA Recording' destination.
- If you want to use an instrument app as a Virtual MIDI App after it has been used with IAA you'll probably have to kill it first.
- Punch-in / Sound on Sound recording: any IAA effects in the track aren't applied to the 'old' signal. The 'old' signal of tracks using an IAA instrument is inaudible.
AudiobusAudio tracks record the Audiobus output instead of the audio input device if you swipe horizontally over the track's Rec button and choose 'Audiobus'. If multiple Audiobus sources are available there'll be multiple options, and they'll contain the name of the corresponding app. Using Audiobus you can record the processed signal of an effect app or the audio output of an instrument app.
Some features aren't immediately obvious:
- Start the Audiobus app before any other audio apps (including MultitrackStudio).
- In the Audiobus app choose 'MultitrackStudio for iPad' in the Output box.
- The Audio Latency setting (in the Studio menu's Devices pane) has no effect when the Audiobus app is running.
- To sync an app using MIDI Clock tap the Studio button and choose Devices. Check the apps you want to sync to MultitrackStudio. Alternatively switch on the MTS MIDI Clock virtual output and pick this as input in the app(s).
- Press a track's name box for a second to rename or remove the track.
- Move a track's name box horizontally to change the order of the tracks.
- Move an effect slot horizontally to move it to a different slot.
- Tap an effect/instrument 'title bar' to move it to the bottom of the screen.
The Pro Extension (available as in-app purchase) adds these features:
- Up to 16 audio/MIDI tracks, audio tracks can be mono or stereo.
