Discussion about the Korg PolySix synthesizer

hi Murray,

Thank you  for your quick response! the memory chip was replaced by  a TC5514APL-3 chip because the old mermory "HM472114-3" consumed a lot of current power ... i have also replaced all capacitor from effect board , and some at KLM 366

ps:when i turn cutoff knob to 10  the problematics sounds seems good ,without noise ...(but I have evidently no   cutoff effect)
