if anyones interested heres a list on the preset pots you'll find inside a Deep Bass Nine that was sent to me by one of the original designers a while back:
Pr1 on analogue board = int. tune
Pr1= span pre-set set to 1 volt per octave relationship
Pr3= filter cut off (set for best filter range)
Pr4= Resonance Q control (set for best resonance 'feed')
Pr5= VCA DC offset null (set for no 'thump' when X waveform and max volume
are used)
Pr6= VCO hi freq trim (DOES NOT WORK !)
Pr303= The trim that makes the DB9 sound the same as a TB303 (sadly taken
off ,just before production run). ;)
I was a little annoyed about Pr303 i can assure you :)
