4MS Atoner Eurorack Module DIY Build

4MS Atoner Eurorack Module - DIY Build

For our latest eurorack build, we take on the mystical Atoner by 4MS Company. This little beast is only available as a kit that can either be ordered from 4MS directly or through other DIY module shops. We picked up ours from the gang out at SynthCube and dove right into the build.

As for the build itself, it was relatively straight forward thanks to the extensive BOM and assembly guide that were provided with the 4MS Atoner kit. Where the build can wonder into the intermediate build category is with the tight ground wiring and navigation of confined spaces (see photos). With that being said, make sure your iron is clean and primed correctly as you don’t want to go into this build with a dirty iron or a dull tip. As for aesthetics, we loved the graphic design on the panel but didn’t care for the knobs that were supplied with the kit. They looked like generic cheap knock off Davies clones, so we chose our own orange Davies Clones to give our 4MS Atoner a little more flavor.

So what exactly is the 4MS Atoner and what can it do for your rack? According to the companies website the 4MS Atoner is a “unique and versatile device used for creating quantized melodies tuned to an input frequency”. It can also generate poly-rhythmic clock and trigger outputs and be also used as a pitch shifting module based on harmonics. The companies site also goes on to state that it is used for “general mischief and mayhem” which from what we have experienced with it, is true.

4MS Atoner - Features and Specifications

Features of the 4MS Atoner according to the 4mscompany.com website:
“Harmonics are extracted from an on-board oscillator or external audio signal and outputed as audio or clock pulses. The Position knob sets the cut-off frequency, under which all frequencies will be stepped downwards along a harmonic sequence (octaves, 5ths, 3rds, etc) all the way to sub-audible clicking sounds. Thus, a scale or clock signal can be generated from a single tone.

Two CV inputs and their respective +/- Vary Amount knobs modulate the Position cut-off. The mix of the two CV inputs plus the Position knob is outputted on a CV jack, and another CV output jack provides a steady +10V clock pulse that is jumper-selectable to be a clock division of the audio output (/1, /2, /32, /64, or non-linear division).”

Additional Build Notes

At first glance and first use, the module can seem very overwhelming, but thanks to 4MS, they have also created a very detailed little cheat sheet for you to start out with. You can view it by clicking here

We look forward to spending more time with our 4MS Atoner and plan on putting it to vast use with our current rack setups.

Laurentide Synthworks VG2 Eurorack Module Kit

Laurentide Synthworks VG2 Eurorack Module - DIY Build

Laurentide Synthworks VG2

Laurentide Synthworks VG2 is a Passive Dual Vactrol Gate meaning no power is needed to get some awesome sounds out of this eurorack module!  Each Vactrol Gate on the VG2 has 1 CV Input (gate, envelope, LFO, etc.), 1 Audio Input and 1 Audio Output. The CV Input hits the Vactrol LED, allowing whatever audio to pass through. In addition, there is a simple Low Pass Filter applied to the Audio Output with an amount (i.e. Cutoff) knob. As this is a passive circuit, it will not give you full cutoff control, but it does allow the calming of brash wave shapes. There is also an LED at the CV Input for a quick visual reference of the incoming signal.

Keep in mind that a passive circuit using a vactrol can cause subtile differences in tone and output sound. One may be slightly “louder” than the other, or one might have a longer or shorter release time. One circuit could be better suited for drums or percussion while the other might process harmonies or sequences more to your liking. That being said, each vactrol or VG2 is unique in its sound.  Being that the Laurentide Synthworks VG2 is available as a DIY kit only, this gives the builder the opportunity to tweak some of the resistors and vactrols and thus making each individual build unique in itself.

During our build, we began by installing all of the supplied resistors and vactrols as recommended. As we dive more into the sound of the VG2, we might consider going back and cutting off some of the 1K resistors. It all just depends on how and what we decide to use it for in the end. The VG2 was supplied with white Davies Clone knobs, we opted to use Blood Red Davies Clone knobs to give our VG2 a more fitting look. (It matches their company logo better!). The build itself was relatively quick and to the point as we completed this module in under an hour. Laurentide Synthworks also provides some basic instructions on how and what to populate in the appropriate order via their website. We really didn’t follow the guide and just jumped right into this simple build. When it was all said and done, we popped it into one of our racks and off we went. For 49$, this kit is a must have in any Eurorack rig.

Additional Build Notes

Important Note: As this is a passive circuit, it is advisable to use a Buffered Multiple before the CV Input to maintain voltage/amplitude, especially if you are using the top CV to drive both gates. Laurentides website advises that “whatever is sent to the CV jack on the top gate is also sent to the CV jack on the bottom gate. The downside to this is there is a slight voltage drop causing the both outputs to be slightly quieter than if the CV was only driving 1 gate. If you are only using one the inputs and have something against using the bottom gate, you can plug a dummy cable into the bottom CV, or completely disable it by cutting the trace”. 

Instructions on how to do this on available via the Laurentide Synthworks website or by clicking one of the links below.
