Hi - bought a kordbot used on reverb. Wasn’t in the greatest shape, but was working with my op1. I went in to use it on my Digitone for the first time & I can get past the main menu. Tried encoder A, tried about everything I can think of. Reinstalled the latest firmware. Encoders scroll back & forth to play, sequencer, system, etc - but I can’t press any. Half of the keyboard lights up, other half doesn’t.
