In the last few days, the board has started to trigger on it's own without ANYTHING plugged into it. I unplugged the drum pads, even disconnected all ribbon cables but the board is still triggering very fast when I plug the usb in. The second HC4851 is getting really hot, I don't know if that has anything to do with it.
I thought maybe it got shorted somewhere somehow but I can't find anything obvious. None of the caps look blown.
Has this happened to anyone else? What should I do?
I have Synthex V3.2 56i.
Would be grateful for any advice.
