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?

Links and more links…

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.


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…

Below are a series of links that have been provided by Reverse Landfill to help assist with the use, building and patching of the Monotropa v3.

If you are building an older version of the Monotropa, you will have use this link to see all of the versions previous to and including the v3 (this build).


Reverse Landfill Aconitum Noise Mixer – DIY Build

Reverse Landfill Aconitum Noise Mixer - DIY Build

We are HUGE fans of Reverse Landfill and their modules and we were lucky enough to pick up the Aconitum CV mixer module prior to it being discontinued. This noise mixer module has 3 types of analog noise which include white and 2 colored typed with adjustable bass and treble knobs.

The noise outputs are also normalized to the volume knobs and if nothing is patched in, these outputs control the noise volume. At only 8HP, the Reverse Landfill Aconitum Noise Mixer was our first build of 2021.

As with any Reverse Landfill module, Martijn (the owner) provides excellent documentation via his website. You can download the Aconitum V2 Build files here or on the main Reverse Landfill website. After you download the build files, it is important to read the BOM carefully. There are no fancy graphics showing components so you will want to make sure you know how to read a BOM.

If you don’t know how to read a BOM, you might want to go ahead and turn away. Martijn’s modules are for the intermediate to advanced builders and novices will want to take a backseat on these until they have a little more experience. Now, enough with all of the intro stuff… you know how we do this… on with the build!!

Resistors and Capacitors...

First up are the resistors. The resistors are all individually labeled so it is easy to see what is what. If you are unsure, either use a component tester or a multimeter to test the values of the resistors. There are 22 resistors total and placing them is quick and easy. We used top down soldering on the resistors to help speed up the process of tacking things down……
