pajen has introduced an unofficial firmware that adds new features to the Korg Volca FM, including velocity sensitivity, and fixes some outstanding bugs. This video, via ranzee, demos the changes.
The original alternative firmware added velocity sensitivity. Here’s what’s new in the latest version:
New features:
Global setting 9 : enable/disable velocity on MIDI notes IN
Global setting 10: Yamaha compatability/Korg proprietary single patch import/export
Global setting 11: Patch change notes on/off
New MIDI CCs:
CC 1 : (Mod wheel) assignable via CC 91, defaults to Pitch Mod Depth
CC 85: Chorus on/off. value -64 off, value +64 on.
CC 86: Chorus stereo width, 64 is default
CC 87: Chorus speed, 64 is default
CC 88: Load patch, value 0-4: patch 1, 5-8: patch 2 etc up to 127
CC 89: Load pattern, value 0-8: pattern 1, 9-16: pattern 2 etc up to 127
CC 90: Tempo divisor, value 0-31: 1/1, 32-63: 1/2, 64-95: 1/4, 96-127: 1/8 (!)
CC 91: Mod wheel mapping: decides what MIDI CC mod wheel should map to. Example: value 42 sent on CC 91 – Mod wheel now controls Modulator Attack
LFO fixes:
S&H 256x scale error
S&H update logic error
LFO sign error (saw up/down, square polarity)
added filtering to remove digital pop on discontinuous LFO
