Synthrotek VCO – DIY Build

Synthrotek VCO - DIY Build

As you get more and more involved in the modular world, you will hear the statement “you can never have enough VCO’s” We have found that this statement is very true and it was time to add another to our rack… the Synthrotek VCO from their slider series of eurorack modules. VCO’s or otherwise known as Voltage Controlled Oscillators are a must have for any modular artist as they are often used for drones or other audio sources.

Compact and backed by the Curtis CEM3340 reissue chip, the Synthrotek VCO is an analog voltage controlled oscillator with a wide frequency range and 8 trackable octaves. Let’s get onto the build…

The Build...

One thing you will notice with the Synthrotek VCO kit is that it is a partial kit and not a full on DIY kit. A “partial” kit usually means that most of the tiny stuff has been already soldered and you only have to solder the bigger hole-through components; this kit is just that.

Please note …. this doesn’t mean that the kit is for beginners though!


Synthrotek Dual Low Pass Gate – DIY Build

Synthrotek Dual Low Pass Gate (LPG) - DIY Build

SR LPG - Completed Module

Lately, we have been on a kick with the slider series from Synthrotek and for this build, we took on the Synthrotek Dual Low Pass Gate (LPG)! If you were to ask any modular artist if they had a LPG in their rack, 9 out of 10 artists would answer with a yes. It is a staple in modular racks and this is especially so with West Coast Synthesis. Synthrotek kicks it up a notch by giving us not one, but two low pass gates in one 4hp module.

 Another badass thing about this module is that when you are not using at an LPG, you can use it as a VCA! (one can’t have enough VCAs!) When in VCA mode, it bypasses the low pass filter and resonance leaving color out of your audio input. 

The Build...

Before we jump right into the build, take a minute to deconstruct the kit itself. Synthrotek does and always has offered outstanding documentation and reference material on their website. They have also included a visual BOM with the kit to help move the process along.

Being that the Dual Low Pass Gate is apart of the slider series of modules released by Synthrotek, this module would sport the same beautiful slider pots and sleek black panel. We recommend that you have some soldering skills prior to taking on this build. Even though its not really an advanced build, it does require a very steady hand and clean iron (also the board mating can get tricky if you jump the gun).
