Well well.. Here we go again with the next polysix.. It has the same problems as the earlier one:
-sub osc doesn't work(one of the octaves actually works)
-octave doesn't work
-waveform switch doesn't work
-Pwm doesn't work.
-Modulation to vcf/vco doesn't work.
And also: the effect section is always on in one setting
in the near future I'm sure I'll fix it..and one of the osc is always hanging. The LED is constantly lit. Might be a problem with the keyboard though..
But the weirdest part:
When I the the attenuator/gain pot the presets switch back and forth!?!?
Does this indicate a broken CPU? Because if it is broken then I suspect it's not worth repairing the rest of the synth..
Pretty big project, eh?!:)
