Problem: Spontaneosly changing parameters

[OSCILLATOR2]

Hello,
I've had really good time with my EMX-1 for 5 months now. Unfortunately, I was having a live performance and after that there has been some annoying problems with my gear.
Basically, the EMX-changes parameters (cutoff, eg time, resonance) spontaneosly. It doesn't happen every time and rebooting once or twice helps. However, I'd really liked to try to fix this problem. I do not understand the hardware in EMX so well, could it be that some solder joint has disconnected?

I take my EMX to guy who knows a lot about radio electronics, but do you have some hints to troubleshooting?

Best regards,
Oscillator_2.0

I have The same problemas, with eg time... No way to solve.. I cleaned The knobs and helped a bit bit comes. Black once IN a while. I temporaly solve The issue by tweaking The knob gone wild, applying The changes to a fandom and unused part

I fixed this by disconnecting and reconnecting the ribbon cable from the arp to the lower board . Make sure every thing is seated well and the keeper is pushed up tight
