Description

This is the newest ADDAC VCO, the original ADDAC701 oscillator was discontinued a few years back and since then they’ve been wanting to release a more stable version with better pitch tracking – increasing pitch reliability and further minimising the detuning issues of analog VCO’s.

For this new revision ADDAC chose to use the modern version of the CEM3340 IC from CoolAudio and have added the triangle-to-sine circuitry of their previous VCO. This new version is extremely stable over 7 octaves.

This oscillator also features a new Mix section which allows mixing of all waveforms controlled by the 3 knobs in the middle of the module.
