MIDI adapter for the KO-33 Pocket Operator

Genius! The guy is making a detachable MIDI adapter for the KO-33.

Hat tip to Sonic State for spotting it first.


Im making the same thing but with BLE MIDI and ESP32.Its easy to power it by PO. How ever I can only up to do 16 physical outputs. :confused:

very cool! HanzTech makes a similar device - I have one, works great and is also a usb midi converter

the only downside is that since pocket operators don’t play a full 12 note scale it can be of limited use depending on what you’re trying to do, and also depending on the PO model


Very impressive and cool project ! I like your set up !


anyone have suggestions for a 23~25 pad midi controller for this? +2 knobs ftw
