Feel free to ask if you need any assistance, though i think the manual is pretty straight forward. I have designed following modifications for the Old School:
– Filter Pole selector (1,2,3,4 poles)
– VCO PWM enable/disable option for sub osc emulation
One sunny afternoon, drill, soldering iron and couple of IC sockets is all it takes.
It is that simple!
