MRG VCO

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

It has been designed from scratch, with some unique analog circuits. It is one of the most loved MRG modules, and its sound has impressed many owners of other 3340-based VCOs for its sound.

The VCO is meant for subtractive synthesis, and outputs SAW and PWM signals, the two basic waves containing more harmonics.
