1. Vocal Pitch Correction

The audio track editors feature vocal pitch correction. You can select a part and apply pitch correction. If the vocal track has severe pitch problems you can exclude notes in order to avoid correcting to the wrong notes. This can happen if the vocals are so much out of tune it's closer to a neighbouring note than to the intended note. You can even use a MIDI track to specify the notes. This allows for changing the melody.

2. Audio pitch shifting / time stretching / warping

We have licensed DSP Dimension's Dirac Pro pitch shifting / time stretching technology. The audio editors use this for transposing and time stretching/warping. Vocal Pitch Correction is powered by Dirac Pro as well.

The selected part can be transposed via the Edit Control (see picture above). There are two algorithms available: Polyphonic (default) and Monophonic. It's recommended to switch to Monophonic if the track is monophonic: it's faster and it sounds better. The stretch and warp functions also use this algorithm.

Resizing the selected part while the Alt key is pressed stretches (or shrinks) the part:

Stretch Stretch
Stretch (use Alt key), before and after

The part can be 'warped' using the Alt key as well:

Warp Warp
Warp (use Alt key), before and after

The Tempo editor can optionally change the tempo of audio tracks. The Tempo editor also features 'warp', just like track editors: any grid line in the selected part can be moved:

Warp in Tempo Editor Warp in Tempo Editor
Warp in Tempo Editor (use Alt key), before and after

3. VSTi plugins can run 'bridged' (out-of-process)

64 bit versions of Windows support over 4 GB of memory. MultitrackStudio, being a 32 bit program, can use only 2 GB. That's usually no problem at all because it's next to impossible for MultitrackStudio to require that much memory. There's one exception: sample-based VSTi plugins. Some of them can use hundreds of megabytes for just one instrument. If you use several of those you'll want to use all the memory your computer can provide.

To work around this limitation VSTi plugins can run 'bridged', or 'out-of-process' in computer lingo. Each bridged plugin can access up to 2 GB of memory.

To run a plugin bridged you can right-click it in the instrument selector, and check the Run bridged option. From now on, all new instances of the plugin will run bridged. The window title bar of a bridged plugin reads "VST pluging (bridged): name".

4. Other

  • Audio/MIDI editors can reverse the selected part.
  • .aem files: you can now browse for any missing edit files.
  • Audio scrubbing tries to keep original pitch.
  • MIDI: improved handling of overlapped unison notes (in MIDI files and while playing back)
  • Pianoroll: "Join Previous Notes" is now "Merge Notes", and can merge more than two notes.
  • The lower editions now have some features which used to be Pro Plus only. Most notably, scrubbing is now in all versions, and the Professional edition now comes with the Wheel Organ and Electric Piano.
  • A couple of bugs have been fixed.
