Reverse Landfill Veratrum – DIY Build

Reverse Landfill Veratrum - DIY Build

Reverse Landfill’s modules never cease to amaze us and lo and behold they have done it again with the Veratrum; a noise and texture voice with brutal chaos. What is it you ask?

The Veratrum was a intership project between Reverse Landfill‘s own Martijn Verhallen and Freek / FRUKU. It took over 4 months to develop and in the end the Veratrum Noise Module was born. 

Veratrum contains 5 oscillators that go through a “pseudo” ring modulator and this in turn creates chaotic drones and swarming sounds. It has 2 audio outputs (square swarm & filtered) and one LFO output which when used at really low frequencies, blips and clicks seemingly are on the attack.

The Reverse Landfill Veratrum eurorack module also features two touch pads that control the volume and pitch of two oscillators. Its unique look and cryptic control surface mirror that of its brethren modules produced by Reverse Landfill. Now let’s get on with the build shall we?

Below are a series of links that have been provided by Reverse Landfill to help assist with the use, building and buying of the Veratrum.

Of course, we are here for you as well if you have any questions while building the module. Just hit us up on our Contact Page.


Erica Synths Modulator II – DIY Build

Erica Synths Modulator II - DIY Build

Completed Front - Modulator

Following our last build of the Erica Synths Mixer II module, we decided to go back to back by taking on the Erica Synths Modulator II. This DIY module is essentially an LFO with simultaneous triangle and square wave outputs. It is a clockable S&H module with external CV input and noise source. It is also one of the new kits currently being offered by the gang over at Synthrotek.

Apart of the DIY series from Erica Synths, the Modulator II is unique in that it not only has one noise source, but two. Noise sources come in the form of “backpack” PCBs that one can swap for different tones of noise. You have the choice of transistor-based or Zener diode-based noise generator for massive, full spectrum white noise.

As you start this build, it can easily feel overwhelming upon cracking open the kit being that there are multiple PCBs and a bunch of components. Synthrotek did a great job on this kit by providing a clear BOM which we have scanned and linked below. They also separated all of the components for each backpack PCB so that the parts could be located quickly and partnered with the correct board.

IMPORTANT: Before we jump into the build, take note that this is not a build for novice builders. This is due to the very tight soldering pads, poor layout of the silkscreen and one’s ability to read a BOM. You do not want to go into this build not knowing how to read or build from a BOM, being that there is little to no step by step assembly instructions.

The Erica Synths assembly guide is really generalized compared to most DIY build guides we have seen from other companies (but hey, thats why we are writing this up and recording our videos).


Erica Synths Mixer – DIY Build

Erica Synths Mixer II - DIY Build

The Erica Synths Mixer II is part of the DIY series that are now being offered by Synthrotek. Of course, when we heard this, we had to reach out to our friends in the shop to see if we could get irons this kit. A couple of weeks later the kit arrived and we anxious to get it into the shop and in our rack.

So what exactly is a mixer…?

A mixer is literally just that. It mixes whatever you put into it into something with all parts combined. We know how simple that sounds, especially if you think of it like cooking or baking terms. A mixer, mixers the ingredients together to make something else. 

Erica Synths simple describes the Mixer II as a “simple, straight-forward audio mixer” and that the Mixer II is an “essential part of any modular setup.” This is where Erica Synths could not be more correct. A mixer is an essential part of any music recording whether it be via a studio rack, performance rack or recording console (aka. mixer); you need it to mix your ingredients into something else. 


Reverse Landfill Monotropa V3 – DIY Build

Reverse Landfill Monotropa v3 - DIY Build

When it comes to unique and must have modules for our rack, Reverse Landfill is one of the top manufacturers on our list. This month, we are following up our Aconitum Noise Mixer build with another Reverse Landfill aptly called the Monotropa.

This diy module one of the Monotropa’s currently being offered by Martijn. The other version of the Monotropa is known as the Monotropa II or mk2 and is also available via the Reverse Landfill ETSY shop.

Monotropa - Completed Front

At its core the Reverse Landfill Monotropa is a feedback EQ distortion module or basically a bad ass mother f*cker. It consists of 4 pots for frequency volume, 1 pot for feedback amount and 1 pot for gain amount. Since this kit is the 3rd version of the original Monotropa, several revisions to the layout and panel have also been updated. These are subtle differences but they make one hell of an impact.

To sum up this module, it can make any sound bigger, add bass, mids and highs with resonant qualities. In other words, it can completely destroy your beats and percussion which is EXACTLY what we were looking for. Would this module be love at first patch? Let’s see…
