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.


Error Instruments TOMO (Ketchup) – DIY Build

Error Instruments TOMO Eurorack Module - DIY Build

When it comes to unique modules in the Eurorack world, a few names come to mind. One being Error Instruments located in the Netherlands. The owner, Paul Tas is like a mad scientist when it comes to his creations and the new Error Instruments TOMO is no exception.

The TOMO is a new 12HP touch interface CV/gate controller for eurorack synthesizers. Originally released as a stand alone module, the “Ketchup” version of TOMO finds its way into DIYers hearts. We picked one up immediately after hearing of its release. 

So whats with the TOMO names?​

Ketchup, Toxic, Blanks, TOMO … these are all different names for the versions or panel colors of TOMOs. The Ketchup is the only DIY version and basically matches the color of our favorite dipping sauce. This is the kit we assembled for this review and build video. TOMO Toxic is a yellowish green color and TOMO blanks is a white version of the glitchy touch controller. 

The original TOMO panel comes in a black and is still readily available if you are interested. They are all available over at Pauls ETSY shop.

Enough with all the filler, let’s get onto the build!
