I got my synth back - still has the same problem even after they supposedly replaced every single part in it. This is getting ridiculous. I don't know why they can't reproduce the problem. Maybe it is something with my other gear, although I believe I logically eliminated that possibility. Maybe I'll take it to a friend's studio and see what I can find there.
All I want to do is marry a virtuous, traditional Catholic supermodel and synthesize things. Is that really asking so much!?
