Overlooked Module #14: Synthrotek CF Crossfader

video upload by Musical Miscellany

"It's been a while since I've posted an Overlooked Modules episode. Today, I'm taking a closer look at the Synthrotek CF (Crossfader). This completely passive 2hp module is one every wiggler should own. It's not only handy to fill small gaps in your system, but it's genuinely useful in your patches. And since it's passive, you don't even need rackspace to use it.

Post Rearrangement Modular Synth Test

video upload by John L Rice

"Seems like I can never commit for very long on what modules I have in this case. Currently it’s mostly modules from Synthrotek, Division6, and George Mattson. #modularsynth #eurorackmodular #eurorackmodular"

Quick Test After Korg MS2000R MIDI Switching Modification

video upload by John L Rice

"In this custom case of eurorack modules and a Korg MS2000R I have a custom interface module that brings all of the MS2000R’s inputs and outputs to the front. Last year I added a switch to the panel to select MIDI from either the panel’s input jack or what ever is plugged into the Synthrotek MIDI To Cv module. Today I added a behind the panel connection from the Division6 / Mattson SQ816 sequencer to the custom panels’s MIDI input so I can dispense with using an external cable. #eurorackmodular #modularsynth #korg"

Overlooked Module #11: Synthrotek AstroNoise

video upload by Poorness Studios

"This is the next video in my Overlooked Modules series and I'm showcasing the AstroNoise module from Synthrotek. It's available as a DIY kit or a completed module and it contains a plethora of arcade-like sounds. It can be a glitch module, a drone module, a percussion module, or whatever else you want it to be."

Ambient Explorations pt.32 (Atari Punk Console DIY Synthesizer)

video upload by Piotr Garbaczonek

"I decided to start learning about how to build DIY synthesizers, and the basics of circuit bending as a whole, so as a complete noob in all of this, I bought an Atari Punk Console DIY synthesizer kit on synthrotek. I spent probably close to 7 hours on this simple build, just because I never soldered anything in my life so it took some troubleshooting at some point, but I managed to get it working somewhat. I will be making videos about DIY synthesizers and time-lapses and whatnot of my beginner experiments, and such. For now, I made this 'ambient' piece with the 'Quinoa Punk Console'. I thought it would be funny if I put it into a used box of Chewy granola bars, instead of a normal box.

Here are some links of mine:

Synthrotek Atari Punk Console: Build & Demo

"It's time for some more DIY fun! The good folks at Synthrotek sent me this APC (Atari Punk Console) kit to build and review. This is a very simple circuit but it can yield some impressive 8-bit tones. I used a cookie bucket from last Holiday Season to house the unit. It really came out nice.

Klangbau Köln Eurorack: Analog FM, Filter Pings & Wavetable Synth Sounds #TTNM

Published on Apr 21, 2019 THE TUESDAY NIGHT MACHINES

"In this video I demonstrate a patch combining analog FM, filter pings and digital wavetable oscillator sounds.


Klangbau Köln Website:

Patch Notes:
The patch is a combination of four sounds, mixed together and sent through a VCA and audio effects.

1. XR-VCO (big version) sine wave output with added linear frequency modulation from the Variable qVCF's LP output in self-oscillation
2. Variable qVCF BP output in self-oscillation
3. Twin Peak Filter Pings modulated by the Wavetable VCDO audio output
4. Wavetable VCDO audio

All sounds are mixed with a Doepfer A-138 exp. audio mixer and sent into the Klangbau Waveshaper module, although only to use its clean (non-waveshaping) VCA, modulated by the Klangbau ADSR envelope.

The ADSR is trigger by the Pulse 2 output of Klangbau's Rob Hordijk Benjolin, which is sometimes FM'ed by its own chaotic Rungler CV.

The Pulse 2 output also triggers the digital version of the Klangbau Logistic Equation (Logistische Gleichung), which generates chaotic pitch CV for the XR-VCO, qCF and Wavetable VCDO and also pings the Twin Peak Filter's audio input. The CV is also used to modulate the Wavetable DCO's waveform choice.

After the VCA, the audio runs through the Synthrotek EKO Delay, which is modulated by the Benjolin's Rungler, and then through the Klangbau Köln Spring Reverb."

NANDAMONIUM 2019 - RAW Sounds Demo Euroack

Published on Apr 1, 2019 synthrotek

"Low pulsing drones, dive bombs and high-pitched laser sounds! This drone monster has six square wave oscillators with a delay, essentially combining two 4093 NAND Synths and one Cosmic ECHO.

The Nandamonium has two SAG CV inputs. When the CV jack is patched and the switch is toggled to "CV," the NAND circuit is powered directly by the incoming voltage. Beyond controlling pitch, the incoming CV can also be used to create lofi rhythmic effects.

Dial in your drone with the Nandamonium!


Six tunable square wave oscillators and two level controls
Delay rate, mix, and feedback controls, with touch control over the rate and mix
Warp switch: adds a bright, "small" speaker tone
Blast switch: introduces max feedback into the circuit momentarily, great for adding rhythm and strange sounds
Two SAG CV inputs, one per NAND synth
CV/On Switch allows selection of CV control or internal power control (1 switch per NAND synth)
3.5mm jacks
Module width: 38HP
Module depth: 22mm
+12V current draw: 15mA"

Alchemical Audio Touch Controller

Published on Dec 14, 2018 synthrotek

"The Alchemical Audio Touch Controller is a 60HP Eurorack or standalone touch keyboard interface with portamento and pitch bend controls.

If you're looking for something to add to your Moog Mother 32, look no further! At 60HP (12 inches) wide, it's the same size as a Mother 32 or DFAM, and will fit into Moog's tiered rack case. It will also fit into Synthrotek's 6U or 9U Cheeks of Steel. If you want to use it as a tabletop unit, it looks great in our Bus Cheeks.

Touch Controls:
The keyboard pads are shaped and positioned so that a "finger drumming" technique can be developed that is very fast compared to the traditional keyboard, which requires a series of mechanical events to trigger the circuit, string, tine or whatever. Notes are triggered instantly when a fluctuation of capacitance is received. Why 25 notes? It just seemed conventional, and it fit perfectly into a 60HP Eurorack row.
The arrows shift the pitch an octave up or down at each touch.
The four squiggly lines found above the keyboard "bend" the pitch up or down by a semitone or a full octave.

The portamento/slew/lag glides the pitch smoothly from one note to the next. The LAG AMT knob changes the amount of time it takes to get from note A to note B. When switched to "ON" mode, portamento is always present on a note change. If the knob is turned fully counter-clockwise, the effect is turned off.
The LAG GATE IN jack allows a gate to turn the portamento function on and off. Used with a sequencer, LFO or other voltage source, you can make soulful bass lines and melody variations with ease! The slewing function will only happen when an incoming gate is high, externally controlling when "slides" can happen. If the gate goes back to low in the middle of a glide, the pitch will jump to the last note played.

Monophonic or Polyphonic:
The CV OUT jack covers 8 octaves and is monophonic, great for lead lines or bass lines and easy to integrate with your synths. When one note isn't enough, the MIDI OUT has a huge 10-octave range and is polyphonic, allowing you to play all 25 keyboard pads at the same time if you wish.
MIDI: MIDI data transmits on channel 1. The portamento function is tied to the CV output and will not work with the MIDI out. The pitch bend will work with MIDI so long as the unit receiving the MIDI signal has a pitch bend function.

Synthrotek OBEY | Modular Vignette Series

Published on Oct 4, 2018 File Transfer Protocol

"Playing with the new OBEY module from Synthrotek. OBEY is a dual-function module: one half envelope follower and one half attenuverter / offset generator. I'm using the envelope follower in a feedback type path from the vco which is running through the Fold module in order to modulate the resonance on the LPG. The percussion is provided by two DS-M modules, and all of the sequence is coming from the Division 6 Labs Dual Mini Sequencer."
