Now my X0xb0x only wants to play the same note over and over again. I am afraid I damaged the op-amp AN6562 in IC23.
Do you think this could be the problem or did I mess something else up?
some help would be much appreciated!!

Oh no! While i was adjusting the trimpots I must have damaged something. But i don't really know what happened.

IC23 is on the IOboard. It's comparatively unlikely that the xoxbox would actually "play" notes of that one was dead.
If you have a multimeter you may want to check the voltages on J4; if those are ok then check the voltage on IC11 pin7 when playing notes.
