Same problem here. unable to change the channel. Tried all the solutions (click on default, try to send, reboot the keyboard, reboot my mac,...) 5 times. Keyboard is still sending on channel one. What am I supposed to do now?
When using Ableton "External Instrument", i am able to send via other channels but the Keyboard is also sending on Channel 1. So it's like playing on both channels.
Id like to be able to pick one channel via MCC and switch with 2 mouse clicks. Isn't that possible?
Too bad I already opened and authorized the software so now i may not be able to return, in case of no solution...
Please Arturia, I switched from Akai to your stuff, show some support!
