Hi Frank, No problem, we are always here to help, if we can! Actually, I do mean what I say. Look at the circuit diagram and carefully study IC29 and IC34. You

Hi Andy Thanks for your help! ... I checked control lines P24 and P25 from CPU pins 35 and 36 to pin 5 of IC29 and IC35 (is this what you were referring to?),

Hi Frank, I would venture that you may have not completed your mission with the KLM-367. I would go back and check the tracks and function of the logic at IC29

I own both.... you cant compare them...po8 is all modern with sequencer, lots of memory, complex sounds, polysix is simple, basic , good sounding sounds.....
