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!


Reverse Landfill Creep Cluster – DIY Build

Reverse Landfill Creep Cluster - DIY Build

Completed Creep Cluster Front Panel

As we dive into the fall season and Halloween draws near, we decided to take on a little module known as Creep Cluster by Reverse Landfill . Until recently, little was known about the Creep Cluster as it was only available as a desktop synth. We were very intrigued by the desktop model and were stoked to see Martijn decide to release the eurorack version. 

Upon picking up the module through Reverse Landfill’s ETSY page (listed here), we made sure to read through the assembly guide and double checked the BOM to ensure that we had everything ready once the module arrived from overseas. Thankfully, we had a few single female single header wires/pins (at least 3 are needed) but we did have to order some extra wire for the build. A quick order on Amazon and we were ready to go in a couple days. 

What about the design?

The wooden panel with the Reverse Landfill logo really give the panel a unique look. This is something that Reverse Landfill is known for up until recently, as they now offer black panels as an option. 

As for the PCB panels, they are royal blue with a white silkscreen. Martijn also had a little fun with the PCB as you can see by placing an “Easter egg” on the board.  Now, lets get on with the build!

You Creep!

DivKid Mutes – DIY Build

DivKid Mutes by Befaco - Eurorack Modular Build

DivKid Logo

Have you ever wanted to just insert a quick break or turn off a certain portion of your composition and yet keep the track rolling?  If so, you need to pick up a DivKid Mutes by Befaco for your Eurorack system.

Comprised of four I/O channels and four accommodating 3-way switches, the Mutes goes beyond basic muting. For our final build of September, we take on the DivKid Mutes, and get to learn a little more about what this little 4HP module is capable of. 

A Brief History of Mutes

Anyone who dabbles in the modular world is well aware of a company called Befaco.  They are known for producing top quality modules like the KICKALL, Rampage and Chopping Kinky (just to name a few). Their modules have become a staple to any rack over the past few years. 

Additionally, there is a gentleman by the name of Ben who lives in England and goes by the name DivKid.  He is always in the modular know and is constantly previewing and reviewing new modules over on his YouTube page/webpage. His videos are hands down some of the reasons we pick up some of the modules that we have in our cases. Long story short, these two amazing teams partnered up to create the Mutes.
