Same issue here.
Also, when reverting back to Chromatic mode, step sequencer does not advance at all..
Tried clearing steps, clearing pattern, step sequencer still doesn't advance in chromatic.
Step sequencer doesn't advance on any tracks 1-4..
Did factory reset, still doesn't advance.
Power cycled, no change.
Power cycled again, working again, until a scale is chosen, then these same events happen.
Hope there's a fix soon.
