RK-002/MOD MIDI SETTINGS

Modifier Firmware for the RK-002 (former Volca FM)

If you're reading this message the MIDI system is not properly initialized. Probably you did not allow MIDI access, are not using Chrome or don't have the Jazz-plugin fallback installed (or you are on a mobile device) Please install the Jazz-plugin from here: jazz-soft.net Or enable plugin access and try a refresh.

Note: Devices like the Arturia Keystep/Beatstep pro are showing up like MIDI devices but they do not pass MIDI SysEx messages thus can not be used to update/set the RK-002. If you want to try and extract some individual patches from your DX7 Soundbanks, you can try our DX7 patch extractor here

Select MIDI channel
PolyMUX *1:
Extra MIDI channels
PolyMUX expands device polyphony by spreading played notes over extra MIDI channels. The RK-002 MIDI Response channel is the base channel. Select the extra amount of MIDI Channels in the PolyMUX dropdown. E.G. on a 3-voice polyphonic device, setting one extra PolyMUX channel doubles the polyphony to 6.

Notes

If you want to download the small sysex files which allow the settings to be set offline from a PC/Mac program like MIDI-Ox or Sysex Librarian, you can download them here

Updating to this firmware will keep other firmware's settings in RK-002 memory so you can swap back without problems.
