That’s plenty of amperage. Were you playing through the Pocket Piano’s speaker or out of the 1/4" jack (connected to another device)? What mode were you using (red, yellow, etc.)? ---

Do you get the same behavior when you use built-in speaker instead of mixer? ---

I’m having the same problem. Unit powers up, speaker clicks once normally, no response from the keys. I replaced the battery with a new one, no sound comes out. Even when I control it thru midi, no output. Any luck resolving this? ---
