This is our new VCO; we discontinued our ADDAC701 VCO a few years back and since then we’ve been wanting to release a more stable version with better pitch tracking, increasing pitch reliability, and further minimizing the detuning issues of analog VCO’s.
For this new revision we chose to use the modern version of the CEM3340 ic from CoolAudio and add the triangle to sine circuitry of our previous VCO. This new version is extremely stable over 7 octaves.
We also added a new Mix section which allows mixing of all waveforms controlled by 3 knobs SIN/TRI, MIX and SAW/RECT.
Frequency knob with 6 octave range
Fine Tune knob with 12 semitone range
Octave switch with 6 octave range
1v/octave cv input
Linear FM cv input with attenuator
LFO/VCO switch sets overall frequency range
Soft/Off/Hard Sync switch
Pulse Width control with initial knob and cv input with attenuator
SINE, TRIANGLE, SAW and PULSE outputs
Mix output controlled by 3 knobs SIN/TRI, MIX and SAW/RECT.
This module is also available as a full DIY kit.

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC701.
It has an additional cost and takes 4 to 6 weeks to be ready.
At the moment the ADDAC701 standard panel colour is Black.
A custom colour panel can be done in either Red, Green, Blue, White, Silver Gray, Yellowed Silver, and Dark or Light Bronze.
Print colour varies between Black, White, or Red, Blue and Green. We recommend lighter-tone print for darker panels, and vice-versa.
Please note: we don’t stock custom coloured panels. For every custom order we need to make a single panel order from our panel provider. This explains the panel price and lead time.
This module is also available as a DIY Kit from Thonk, Exploding Shed, Soundofyou.eu and Synthcube.
