Program Change (voices 1 - 128) also user selectable CC for voices 128 - 160
There is also an option for making Program Change enable a part if it's currently disabled.

Key pressure (aftertouch) is internally translated as CC 642 but not currently implemented.

Channel aftertouch is internally translated as CC 641 and is accessed by MIDI learn further translated as CC 129.

Pitch Bend is internally translated as CC 640 and is accessed by MIDI learn further translated as CC 128.


The modulation wheel only affects AddSynth and PadSynth, and then only the frequency LFO depth. Just to make it more confusing, it changes the level from 0 up to it's current (gui) setting only. Therefore if the LFO depth is set to zero the Mod Wheel will have no effect.

User selectable CC for Bank Root Path change.

For more details of bank changes see Banks.txt

Instruments inside banks should always have four digits followed by a hyphen. Otherwise the results can be rather uinpredicatable.

Further details on NRPNs are in Using_NRPNs.txt
