This kit includes everything you need to build the Mkii version of the Turing Machine. You just need to provide the tools and solder. Comes with 1ohp Aluminium Eurorack panel.

Since it was launched in June 2012, the Turing Machine has become one of the most popular Eurorack DIY projects. It is a random looping sequencer that spits out basslines and melodies. It generates strings of random voltages that can be locked into looping sequences. These sequences can be allowed to slip, changing gradually over time. This module was inspired by the long history of shift register pseudorandom synth circuits, including the Triadex Muse, Buchla 266 Source of Uncertainly and Grant Richter’s Noisering.

The 2016 revised Turing Machine has many improvements:

• Rotary loop length switch
• Pulse out
• Two boards, includes Backpack circuit to drive expanders (compatible with old Music Thing expanders)
• Easier to build: a larger PCB in the same width, clock and noise circuits are more robust
• Noise level trimmer & reduced voltage in noise circuit to make circuit more robust with different noise transistors
• Compatible with existing expanders (Pulses, Voltages, Vactrol Mix) but not the BYTES expander.

“I am interested in perceptible processes. I want to be able to hear the process happening throughout the music.To facilitate closely detailed listening a musical process should happen extremely gradually.” Steve Reich, Music as a Gradual Process, 1968.

SERGE MODULAR FOR EURORACK – Under licence from Serge Tcherepnin

“Serge Modular” is an analogue modular synthesizer system developed by French composer and electronic designer Serge Tcherepnin in the 1970s at The California Institute of the Arts. Serge’s vision to create a “people’s synthesizers” led to a unique modular music system with an iconic design.

In collaboration with and under licence from Serge Tcherepnin, Random*Source offers a range of Serge modules, combining the original Serge circuits with the advantages of today’s technology. The modules on this page are in Eurorack (3U) format – modules in the classic Serge dimension (“4U” panel height) and the typical banana jacks can be found here.

This kit is designed to be used with any run of the TTSH kit from The Human Comparator.

This is a partial component kit that contains the harder to find parts for the first revision of the TTSH project. The things you won’t find at Mouser, Farnell, Rapid or the parts which require matching to millivolt tolerances. The optional matched transistor pairs were matched using the recommended Ian Fritz method to within 2mV of each other.

This does not contain everything you need to build a TTSH. The PCB and Panel are only available directly from The Human Comparator. The other parts can be purchased from Mouser or Farnell etc. see full BOM and build docs here.

SERGE VARIABLE RESONANCE FILTER (VCFQ)

The Serge Extended Variable Resonance filter (VCFQ) is probably the most famous filter of the Serge system and one of the essential Serge modules. It is an excellent, extremely versatile general-purpose VCF that provides simultaneous low-pass, high-pass, band-pass and notch (band-reject) outputs combined with unique flexibility. Its trigger in, LOW mode and self osciallation allow a variety of uses from Oscillator to VC processing.

Now – for the first time ever and licenced by Serge – the VCFQ is available as DIY kit for Euro.

We’ve been waiting patiently for some versatile logic options in Eurorack DIY and then three come along at once!

This comprehensive suite of Logic modules will have you creating complex rhythmic patterns in no time at all and allow you to inter-modulate your clock and sequencer modules at yet deeper and mysterious levels!

Discrete transistor XNOR/XOR/NOT logic gate

Discrete XNOR/XOR, XOR and NOT gates.

The resistor-transistor based circuit design gives the module some interesting quirks thanks to the transistors thresholds and tolerances when playing around with different amplitudes, waveforms and frequency rates of the incoming signals, making it fun and useful to explore beyond typical logic gating duties, for example as an audio waveshaper/distortion.

It can be patched as two NOT gates and one 2-input XOR gate,
one NOT gate, one 2-input XOR gate and one 2-input XNOR/XOR gate,
two 2-input XNOR/XOR gates
or one NOT gate and one 3-input XNOR/XOR gate.

Gate one and two has two inputs, the third has one. The XOR out from gate one is being normalled to input 1 on gate two. The XOR out from gate two is being normalled to the single input on gate three (NOT).

Dual discrete transistor NOR/OR logic gate

Two discrete NOR/OR logic gates.

A compact 8-step sequential voltage source in 10hp, with optional 4hp trigger output expander. It works great as a classic 8 step sequencer, but also has a CV addressed mode for more experimental & stochastic results. A further expander to be released later in the year will allow two modules to be chained as a single 16 step sequencer.

RYO kits are extremely user friendly with detailed build manuals and individually bagged and labelled components.

• Classic forward/backward operation using a clock
• Pattern based sequencing  using control voltage levels scaled to each step of the sequencer, this allows the CV waveform you feed it with to determine the running pattern. e.g. a ramp to make it go forward, saw to go backward, triangle for pendulum, S&H’d noise for random etc.
• You could also use another sequencer’s pattern to control the pattern of the VC Sequencer, the possibilities for exploration are many.
• All low latency CMOS and Opamp circuitry. No software, firmware, PIC chips, ATMEGAs, micro processors etc.
• Works up to audio rates. The VC Sequencer therefore functions as a 3 bit hands on waveshaper.

COMING SOON – Expanders to allow chaining of 2 VC Sequencers for 16 step operation and unlimited extra parallel channels of CV or gate/trig.

PATHS – A Cycling Sequential Switch

A 4:4 cycling sequential switch, featuring simultaneous forward/reverse stepping, hold, reset, and an additional voltage controlled mode based on the same design as our VC Sequencer. Also on board are push buttons for each function enabling you to play and perform the switching with a more human input.

This sequential switch will do all your standard 1>2, 1>3, 1>4 or the other way around with great real-time as well as external voltage controllability.

But its when you start playing around with multiple sources and destinations that things start getting fun and weird! You could for instance shuffle around four different trigger patterns to trigger four different percussive generators for interesting variations, or why not 4 oscillators shuffling between 4 different destinations, panned and processed in various ways?

Whatever your sequential switch application might be, we’re confident the Paths is up to the task!

Just like the VC Sequencer it is clockable by very high clock rates and CVable with full audio range. All for your experimental waveshaping duties.

In CV mode there is two CV inputs. The one that shares the reverse clock input is full wave rectified and the one that shares the forward clock input is half wave rectified. It uses an active rectifier without voltage drop or a dead zone around 0V. The steps toggle switch and the red buttons are inactive in CV mode.

When I/O1 is connected to O/I1, I/O2 is connected to O/I2 and so on.

When I/O1 is connected to O/I2, I/O2 is connected to O/I3 and so on, and I/O4 is connected to O/I1.

When I/O1 is connected to O/I3, I/O2 is connected to O/I4 and I/O3 is connected to O/I1 and so on.

A full kit to build a compact, easy to use, easy to build and great sounding distortion module which also works as a VCA, giving an LPG style of character to the sound.

RYO kits are very user friendly with detailed build manuals and individually bagged and labelled components.

The Optodist is based on two Advanced Photonix (formerly known as Silonex) optocouplers that gives its characterful overdriven sound and plucky dynamic response to CV, it is equally at home adding a bit of extra crisp to highs and mids or warming up your lows as it is turning a resonant filter into a howling beast or your drums into crushing carnage. The Optodist comes supplied with the SR3 optocoupler. The SR3 gives a tight, snappy CV response.

Please note that due to the nature of the vactrol-style optocouplers, response behaviour may vary between different factory batches.

Also on board is an LED based limiter circuit which limits the signal thru a set of 4 LEDs which can be seen on the panel, for adding a different flavour to your distortion.

The Optodist Kit is a novice-friendly project, it is a low part count, single-PCB build that only requires the most basic experience in PCB soldering and module assembly. Kits comes supplied with PCB, front panel (PCB material), component kit, knobs, power cable and mounting screws. Solder and tools are not supplied.

Width: 6hp

Depth with power cable attached: Less than 35 mm.

Power: +/- 15 mA

Build Manual

Muffwiggler Build Thread for tech support.

The RYO Aperture is a vactrol lowpass filter and VCA module inspired by the much beloved 292 Lopass Gate from the Buchla 200 series modular system of the 1970s. However, rather than being a straight up clone, the Aperture is a newly developed and reworked design for eurorack modular synths.

Aperture can be used as a 12dB lowpass filter, a VCA or a combination of the two similar to the 292 but also adds a new switchable resonance circuit. This solution gives you no less than 6 different characteristics!

• Non resonant lowpass filter
• Resonant lowpass filter
• Both: Non resonant lowpass gate
• Both: Resonant lowpass gate
• VCA
• 6dB variety of resonant lowpass gate in the VCA mode with resonance on.

The resonance goes from smooth and twangy to increasingly bubbly and acidic to wild and untamed howling towards the end of the pots range. The self-oscillation also lends itself well to creating kickdrums, toms and other percussive sounds.

The result is a very wide range of sound shaping possibilities, from the classic resonant filter sweeps of east coast to the plucky acoustic timbres of west coast synthesis and everything in between.

Also added is a unique “Klang” function. The Klang input generates a decay slope from a trigger, the shape is very steep in the beginning and quickly smooths out to a nice prolonged ring, resulting in a very natural acoustic sounding tone. The circuit was specifically tailored for this purpose and does not give the same result as just using a decay envelope with the regular CV input. Experimenting with different trigger voltage and length will affect the response of the decay and overall shape. It will also work with other control voltages but will add a falling slew to the signal. Trigger the CV as well as the Klang input at different intervals for simulating the impression of striking a drum or string instrument in different ways.

Finally, the input is AC coupled and has a dedicated attenuator with clipping overdrive towards the end of the pot range for adding a bit of extra bite to the incoming signal. The signal input is scaled for 10Vpp audio signals. The AC coupling comes after the overdrive circuit so you can add offsets to your audio with RYO Ampmix and many other modules to get an asymmetric clipping.

THIS IS A FULL DIY KIT

This module is performing real-time LPC synthesis to produce intelligible voice or … not if you choose to.

The module produces sounds in 3 major modes: Speech, Repeat and VCO.
In Speech mode, the speech starts with a gate signal and complete before waiting for a new gate signal. The speech has the priority.

In Speech mode, the speech starts with a gate signal and complete before waiting for a new gate signal. The speech has the priority.

In Repeat mode, the speech starts and stops with the gate signal going high or low. The gate has the priority and the speech repeats while the gate is high. This mode is very useful to create crazy rhythms.

In VCO mode, the LPC engine loops while the gate is high, producing steady notes. The VCO mode can also produce sound using white noise instead of tones, making strange throat sounds.

The sound synthesis can be altered via CV signals to affect pitch, speed, bending.

Talko is an Arduino-based synthesizer developed under open-source hardware and software.
Its firmware can be updated via the onboard USB port.
The module can be powered via USB if needed.
