New version 3.5

Release Notes • Onscreen MIDI keyboard: keyboard, string, drum and matrix layouts are now (optionally) velocity sensitive. • Onscreen MIDI keyboard: Finger Vibrato option no longer makes keyboard and string layouts monophonic (but finger vibrato only works if just one note is playing). • Onscreen MIDI keyboard: keyboard, string and matrix layouts can now generate polyphonic aftertouch (by moving finger upwards). • MultitrackStudio Instruments: bowed strings, winds and synths now respond to polyphonic aftertouch (it increases the volume level). • Polyphonic aftertouch editor names now mention note name rather than key number (ie. 'C5' instead of '60'). • AU Plugin Manager. You can override plugin name, add category to name and change text that appears in slot. And you can hide a plugin from effect, instrument and/or MIDI effect selectors. • SoundFont Manager. You can override soundfont name and add category to name. • AU plugins and IAA apps can now reliably detect MultitrackStudio transport stop. • Now uses Audiobus SDK 3.0.7. • Various fixes and improvements.
