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.
The way it works is simple. Send it a ‘C’ note over a 1v/oct CV signal, hit the button and the module will do the rest. It will calculate the offset voltage needed to bring that C up to perfect pitch. It’s recommended (as with any analogue synth) to let the module warm up for 10 minutes or so before tuning up.
So you may be thinking: “how do I slightly de-tune it to make a fat bass line voice?”.
The answer is simple – Say you want it to be de-tuned by 1 semi-tone; just hold the B note whilst hooked up to the module with a 1v/oct CV signal, hit the button, and it’ll use that as its reference, allowing you to easily tune it perfectly – or de-tune to your hearts content.
Another very useful feature of this VCO is the wave-mixer it’s fitted with. No need to keep removing and re-plugging cables, just turn up or down the Triangle, Square, or Saw-Tooth waves until you’re happy with its beefiness.
