MRG VCO

module

The MRG VCO is an oscillator based on the AS3340 (clone of the CEM3340).

Quality components, polypropylene timing capacitor, and precise tuning make this a small, simple, but high quality oscillator.

1V/Oct CV stable over more than 6 octaves, precise waves, PWM and SYNC input.

Output waves are square and sawtooth.

When no PWM input is present, the square wave has a duty cycle of 50% – this is actually configurable by an internal trimmer.
