PB105 Saw Sync
There is a new version of this oscillator. Please use the PB101 Sync VCO instead.
That is an other version of the PB101 Sync VCO with a switch for shaping the waves. In square wave mode one can change to a super short duty cycle and in triagle mode one can switch the wave form from triangle to ramp. The board itself has some smal mistakes compared to the PB107 Sync VCO II but that makes the sound quit interesting.
