This is a full kit for the Duskwork Self-Tuning VCO V2, including all parts that you need to build it. The PCB comes pre-populated with all smt components, apart from the AS3340-SOIC16 which you would need to install along with all through hole components, and then program the Atmega328 by using the 6 pin ISP header with a provided .hex file. You can find a bill of materials, and build instructions in the build guide located below. You’ll also need to upload the .hex file below too.

This DIY kit would be idea for beginners venturing into surface mount soldering & experts alike.

Duskwork AutoTune VCO (6HP) designed & built for Eurorack systems, requiring an external +/-12v power supply as per the Eurorack standard.

This is the module that every modular synthesizer enthusiast has been waiting for. A VCO that can tune itself. Imagine Cher, but there’s a switch to control her reference pitch… That’s exactly what this module does for you.

The VCO voice is completely analogue, powered by the infamous 3340 IC that many well known synths used back in the 80’s. Here it is, re-imagined, 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 thicker bass line voice?”.

The answer to that is a simple one. 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.
