Discussion about the Korg PolySix synthesizer

Hey, yeah I had no difficulty getting them out. I broke the glue before doing it a few days ago. Don't think there is an issue there. Ive been speaking to the guy who owned and 'rebuilt' it before me. He said - 
 the noise result by lifting the keyboard seems to be the result of a grounding problem. so there must be an interruption of the grounding all over the synth. not funny indeed. i would check the result by removing the MIDI board. you can connect the keyboard also the original way - no cables are modified as i remember. So check this first. maybe it is injected by the MIDI board - only a suggestion of mine.
