"Just had it recently serviced, everything works on it except for the aftertouch. If you look at other Arp Qudra's the aftertouch does not work on them, this is a known issues with these. Once the aftertouch dies it cannot be fixed. The tech that I had work on it works on modular moog synths and if it could have been fixed it would have been fixed, he said there was no way to fix the aftertouch. Another known thing about this board is that if the keyboard is not on a flat surface the membrane can act funny and some of the buttons light up when not pressed, all Arp Quadra's are known for this. As long as it is on a stable surface it should be fine. I had mine on a keyboard stand and it worked fine."
