The Duskwork Analogue VCO has the feature that every modular synthesizer enthusiast will appreciate – a self-tuning button!

This VCO voice is completely analogue, powered by the infamous 3340 IC that many well loved synths have used since in the 80’s. Here it is, re-imagined and assisted by a computer controlled circuit that will tune the VCO all by itself.

To tune the VCO – connect a v/oct keyboard to the CV input, hold down a C note on the keyboard and hit tune – wait for the green LED to light up again, and then it will be perfectly in tune. This updated version of the VCO now has its own manual fine tune knob in addition to the Self-Tuning function for the ability to detune. It’s recommended (as with any analogue synth) to let the module warm up for 10 minutes or so before tuning up.

Another useful feature of this VCO, is the in-built 3 wave mixer. You can mix the 3 waves to your preference; Triangle, Saw-Tooth & Square. Each wave has its own signal LED so that you can tell how loud each wave is at just a glance. There is just one audio output, so no need to keep moving cables if you wanted to change the oscillator source sound.
