Digitakt & Korg Volca FM - patch notes

Current Live Rig

I'm using a Volca FM 1 with Unofficial Firmware 1.09
The new firmware is excellent
I'm sending CC values from the digitakt to the FM

Possible CCs

TRANSPOSE 40*_Val 1
VELOCITY 41*_Val 2
ALGORITHM 48*_Val 3
CC 88: Load patch, value 0-4: patch 1, 5-8: patch 2 etc up to 127_Val 4
MODULATOR ATTACK 42*_Val 5
MODULATOR DECAY 43*_Val 6
CARRIER ATTACK 44*_Val 7
CARRIER DECAY 45*_Val 8
ARP TYPE 49
ARP DIV 50

CC 1 : (Mod wheel) assignable via CC 91, defaults to Pitch Mod Depth
CC 85: Chorus on/off. value < 64 off, value >= 64 on_Val 1.
CC 86: Chorus stereo width, 64 is default_Val 2
CC 87: Chorus speed, 64 is default_Val 3
LFO PITCH DEPTH 47*_Val 5
LFO RATE 46_Val 6
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


Remember that the Digitakt has 8 MIDI channels (A-H)
Of course you can have multiple channels running at the same time sequencing
the one Volca.
These different channels can have different CC sends.

The CCs I picked for MIDI channel A are labeled with Val 1-8
The CCs I picked for MIDI Channel B are labeled with Val 1-8



You will notice that once you have mapped a CC
to the Volca it's LED will light up everytime it receives a CC from the digitakt
(apart from transpose & velocity)

Once you have done this you can also map it to the Digtakt's LFO



This CC is useful:
CC 88: Load patch, value 0-4: patch 1, 5-8: patch 2 etc up to 127_Val 4

You can load a different patch / preset with each pattern.
Or you can control this with a LFO / randomse to change patches on the fly
