MIDI mapping of Korg Volca FM operator editing functions

greencore · Post by **greencore** » Sat Apr 14, 2018 12:34 pm

Hello everyone!

I recently got Volca FM (firmware 1.0.4) as a gift and I want to map operator editing functions on my M-Audio Axiom 49. I was able to map global controls like velocity, modulator attach etc. successfully but I have no idea how to do that for operator editing. I found this document https://soundprogramming.net/manuals/Ko ... tation.txt and I see that there're two tables with "Voice parameters". My guess that there is one control where you send 1-127 number to select operator option and another control that sends value for that parameter. Even if I'm right I don't understand how to do that.

Any help would be appreciated!

Hi,

Except if the Volca FM is seriously enhanced in version 1.04 (older models can only update till version 1.03 via the Korg site - Korg did not release 1.04 to us

), you can not edit parameters using SysEx or CC MIDI messages. At least it is not described in any document. The voice parameters in the txt-file that you refer to, describe how a SysEx message is built up to download a complete new patch. This ain't gone work to tweak the sound during a performance.

Too bad, I agree...
