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).


Delta Sound Labs: Saber, Origami & Mobula DIY

Delta Sound Labs - Saber, Origami and Mobula DIY Builds

Delta Sound Labs have been around awhile, but they were not really known for DIY Kits. Their eurorack modules (the Saber, Mobula and Origami) were all available as fully assembled modules which could be ordered at various locations on the web.

We longed for the Delta Sound Labs (DSL) modules shortly after watching a couple of videos about the filters. Since we are DIY guys, we were ecstatic when Delta Sound Labs announced DIY kits in June of 2019.

For our first “builds” of 2020, we took on the three DSL modules in one fail swoop. Each module has its own build video and we encourage you to take the time to watch the videos if you are interested in purchasing one of the kits. 

There are some pro’s and con’s about their kits which don’t make or break the builds, but its information one needs to know.  Now, let’s get on with the builds. 


Synthrotek Roboto – DIY Build

As 2019 came winding down, the gang out at Synthrotek sent us over the Roboto Eurorack DIY kit and low and behold, we were onto another build. The Synthrotek Roboto was originally released in 2017, but has quickly become a staple in a lot of musicians racks due to its versatility and uniqueness. 

From the first module in our rack, we have always had our eyes on the Synthrotek Roboto. We were excited to finally take this one and see what it could do. Roboto is known as a vocoder, pitch shifter, speak-n-spell effect processor, vibrato provider, an 8-bit modulator or plain and simple…  a bit crusher.

Now, let’s get on with the build.


Synthrotek Arcadian Rhythms – DIY Build

Synthrotek Arcadian Rhythms - DIY Modular Build

Completed Module

As the new year draws upon us, we take on a brand new module originally introduced at Knobcon 2019. The Synthrotek Arcadian Rhythms is a touch controller that brings the feel of the retro arcade right to eurorack. 

The design of the module is quite simple. Three arcade buttons, a power header, some standoffs, three jacks, a few resistors and a couple trimmers make up the module. This simple, yet intricate little design gives even the novice builder a chance to take a stab at DIY.

Synthrotek have always had a knack for ensuring that the builder is well suited to tackle their builds. They not only include a BOM with their kits, but they post their BOM and assembly instructions on their website as well.

Now, enough with all that… let’s get on with the build.
