Modding Volca is easy. You can find clear MIDI out marking on the all Volca’s PCB. You just need a 3.5mm stereo female jack and couple of wire.
I decided to use 3.5mm TRS jack rather than old standard(?) 5-PIN DIN connector because:
- DIN socket is hard to fit in housing
- 5-PIN DIN cable is big and bulky
- 3.5mm stereo cable is everywhere
All Korg instruments using “Type A (MIDI 2.0 standard)” so connection should be like below (if you have a Type B gear then google is your friend).
I added 3.5mm MIDI In & Out to Volca Bass too.
