WORNG LRMSMSLR Mid-Side Encoder-Decoder Thonk DIY KIT Build+Patch Test - Eurorack Synth DIY

"WORNG Electronics LRMSMSLR Mid-Side Encoder-Decoder Eurorack Module 'Thonk' DIY KIT Build Steps and Test Patch Video (2018)

Mid/side processing is extremely useful and common practice in mixing and mastering. It allows you to process the Mid Content and Side content of your stereo signal independently. For example, in the patch I used to test my WORNG LRMSMSLR DIY KIT purchased from I use the LRMSMSLR Eurorack Module to add AJH GEMINI 2412 Filtering to the Mid content of my stereo signal and only to the Mid Content. At the same time I am adding Fuzz Distortion only to the Side content of the stereo signal by sending the SIDE signal through the Retro Mechanical Labs Electron Fuzz Custom EFCCV Eurorack Module

But that’s just the start, there is a lot you can do with the ability to press Mid and Side content of a stereo signal, the WORNG LRMSMSLR is an extremely useful tool opening up a lot of creative doors.


00:00 Why I chose this module as a possible first Eurorack DIY Kit to build and why I keep the build simple, rough and quick… DIY Beginners Friendly

00:29 Thonk Worng LRMSMSLR DIY KIT Content - Not many components so we look at the full kit content from Front Panel to Resistors, etc…

01:38 Starting with 1K Resistors - Placing them through the PCB, ways to hold the PCB, Soldering the Resistors,

02:33 Now the 10K Resistors and Cutting Components Legs

03:40 We get started with the Capacitors (22pF x4)

03:52 Now the 6 Capactiors without name on PCB - Located and placed.

04:24 The two Electrolytic Capacitors, these have different polarity per leg, if you are new to this I show you how to identify Polarity on Capacitors and PCB.

05:05 F1 and F2 the two Fuses plus L1 and L2 the two Ferrite Beads

05:26 The two 1N4001 Diodes. How to identify Polarity for the Diodes and on the PCB board.

05:52 Time to fit the Power Pins Header on the PCB

06:15 The 4 IC Sockets placed and soldered

07:19 Time to fit the 8 Jacks pieces. How I keep them all steady then finish soldering all of them in one pass.

08:52 Fitting the Front Panel to the PCB

09:30 Connecting the Power Cable to the Pin Header on PCB (Stripe/Negative)

10:16 Let’s plug those ICs Op Amps into the IC Sockets

10:58 I setup a quick patch and show all the connection. We filter the Mid content and Add Distortion to the Side content of a stereo signal. I enable and disable processing so we can hear the difference

Modules used in this video patch are:
Pittsburgh Modular Lifeforms KB-1 (keyboard sequencer)
MFR OSC-03 Triple VCO
MFB DRUM-99 Drum Mixer
WORNG Electronics LRMSMSLR - DIY Kit we just built in this video

Final LR output from the LRMSMSLR goes into a Mackie 1402 LVZ4 (not needed but too lazy to disconnect it :))… then straight into the Roland GO:Mixer so that I could record the Video/Audio patch through my iPhone for a quick test of the Kit in action to make sure it works.

AJH GEMINI 2412 (CV Controlled Filtering on the MID content)
Retro Mechanical Labs Electron Fuzz Custom EFCCV (Distortion on SIDE content)
Xaoc Devices Batumi (for some free LFO/CV signal sent to AJH Synth GEMINI 2412 and the RML Electron Fuzz Custom EFCCV)

NOTE: The patch I play in the video during the Kit Building section is the same patch as described in the video for the Test Patch, plus the following:

Trigger 1 from Pittsburgh Lifeforms KB -1 triggers Futureretro Transient percussion sounds

Futureretro Transient OUT goes into the AJH Synth Mega-Phase 12

AJH Mega Phase 12 L-Out goes into the hex inverter Mutant Drums Distortion Input

Trigger 2 from Pittsburgh Lifeforms KB-1 triggers a snare type of sound on the Hexinverter Mutant Snare

Doepfer A-147-2 VCDLFO Sine + Manual Frequency control is sent to the 1v/o input on the AJH Gemini 2412

A Sine from Xaoc Batumi is sent to CV Control on the Mutant Snare and on the Pitch CV on the Mutant BassDrum

3 Outs from the MFB OSC-03 + Mutant BassDrum DIst Out + Mutant Snare Out, all mixed into the MFB DRUM-99 Drum Mixer
L/R Outs from the MFB DRUM-99 go to L/R inputs on the WORNG LRMSMSLR
Mid and Side precessed as described above (Gemini 2412 and RML EFCCV respectively)"
