The C23 fix is for clock instability from the ceramic resonator. The original board had 22pF for C23 and 10pF for C22, but the clone board seems to be more

It sounds like one or two of the six voice filters needs to have the resonance turned down a bit. You will have to open it up and watch the internal LED lights
