[sdiy] quick Polysix help—?

[Dan Snazelle]

Hello

I’ve got a polysix here that seems to have all working 2044’s that respond to Mg modulation 

However the cutoff knob
And Resonance knobs do nothing 

only the key tracking knob is effecting the sound (in manual mode)



Also the ADSR knobs aren’t doing anything either (which are on same mux chip)

any quick thoughts on this ? My first thought is a bad 4051 chip but as I’ve never repaired one before I was wondering if I’m overlooking something here 


Already did the converters calibration and tuning calibration 



Going to be looking at it again today 


THANKS
