MultitrackStudio for iPad 3.0 (September 17, 2018):

• MIDI effects (Arpeggiator and AU). AU MIDI effects require iOS 12.
• All MIDI Instruments (except for IAA) now have an option to specify note names. These names appear in the drum editor.
• Articulations for multitimbral External MIDI Instruments and AUi plugins. You can use a MIDI controller to switch between bowed and pizzicato violin, for example.
• Cycling transport: transport bar now has Cycle button.
• 12.9 inch iPad: tracks have Content Panes showing a compact version of the data in the track editor.
• Swipe left over start/stop button to rewind. Also stops transport if it's running.
• SoundFont Player: you can load next/previous soundfont by swiping vertically over SoundFont box (just like you can with the Preset box).
• SoundFont Player: the SoundFont box list now automatically scrolls to the currently loaded soundfont.
• Note Editor pane: you can now type semitone offset in Note box (for example: if it's C5 and you type -2 it becomes Bb4).
• MultitrackStudio Instruments synths: attack is now linear rather than exponential, in order to avoid the synths being noticeably 'late'.
• 12.9 inch iPad: track editors no longer open full-size.
• Level meters no longer have 'LED' segments.
• Editor graphics are more CPU efficient.
• Fixed: Running an audio track in practice mode no longer clears the track editor undo history.
• Fixed: automatic horizontal scrolling while resizing selected part on the right hand side didn't work reliably.
• Various other fixes and improvements.
