Synthrotek ADSR – DIY Build

Synthrotek ADSR - DIY Build

For our latest build, we take on the new Synthrotek ADSR. This ADSR is a small (only 4HP) and simple envelope generator that has a CV additive available in its ADR stages giving it a unique controllability that few ADSR modules have.

It is well known that as one dives deeper into the world of modular synthesis, it becomes apparent that certain types of modules are needed to compose dynamic sound. ADSRs can dynamically change the “movement” of sound due to its ability to alter parts of the sound waves. 

Before we jump into the build, we have to state one thing.An ADSR is a must for any modular artist, and the Synthrotek ADSR is an excellent choice!

What is an ADSR?

By definition, ADSR stands for Attack, Decay, Sustain, Release. It’s a must-know concept for all types of music production and sound design. Together, they make up the ADSR envelope which can alter the shape and sound of audio giving you dynamic music.

This concept of ADSR applies to all sound no matter what kind of source you’re using. ADSR controls are most commonly found on VST synths, hardware synths and samplers. Now, enough with the jargon, lets get on with the latest build… 


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).
