use 50K REV LOG pot for osc periode and bridge wiper to left pin (rearview)
BugtrackBugtracking/Known Build Problems:
if your modulation pot dont doesn´t work, check your wiring at active/bypass switch .and check that you have the Bridge at the OSC Periode Pins (see above) (its also shown in the schematics)
if your sound is have to many middle sound, try other capaciator values (original is 33nF) sometimes 47nf or 68nf sounds better.
Feedback - bridge Pin1-2 in every case on the Random Source PCB for the Feedback path
Feedback not working: don't use Modular Levels (5VPP) for audio input - otherwise FB isn't working as designed.
Bill of Materials (BOM)
