Unofficial Volca FM Firmware 1.08

YouTuber ranzee shows off an unofficial firmware patch for the Volca FM. You can read more about it and grab it from this Reddit thread. The video here covers the major changes, including a fix for velocity. There is a follow-up video showing the update procedure; including update failures.

Video Description:

A new unofficial firmware has emerged which has fixed a number of major issues on the Volca FM. These issues are critical fixes that Korg have missed. The video covers the firmware features and fixes.

I'm not the original author of this firmware (written by Pajen). If you perform this update, it is done at your own risk. You can also revert back to an official Korg firmware.

New features:
Global setting 9 : enable/disable velocity on MIDI notes IN

Yeah, I need to look into this some more. I wonder if the Volca Bass can also be updated. It has always bothered me that there is no volume control for the individual oscillators. I would use it way more often if there were a way to make sure one oscillator isn't drowning the others.
Apparently there's a Volca Sample firmware being tested. Curious to see what they can do with that.
