4ms - Meta Module (Assembled)
available
The MetaModule puts real knobs and jacks on virtual software modules. Step back from the computer and make music with hardware, while keeping the flexibility and expandability of software.THIS PRODUCT IS ASSEMBLED AND NO DIY!The MetaModule comes with over 160 built-in modules from 4ms Company, Befaco, HetrickCV, NonlinearCircuits, and Scanner Darkly, plus clones of popular classics such as the Mutable Instruments Eurorack modules, fun physical modeling algorithms, and lots of handy utilities.All of the included modules are also available on the computer using the free program VCV Rack. Whether you make patches on VCV Rack and transfer them to the MetaModule, or if you just create patches directly on the MetaModule, there are plenty of creative modules to inspire new ways to make music.MetaModule PluginsIf the 160+ built-in module aren’t enough, you can load more modules as plugins. Already there are over 200 modules in third-party plugins from Bogaudio, Valley, ChowDSP, NANO Modular, and the list is growing. We have an SDK available to make it easy for VCV Rack plugin developers to convert their plugin to a MetaModule plugin. Our licensing terms are non-restrictive: developers are welcome to distribute their plugin in any way they wish, commercially or not.Mapping Knobs and JacksThe MetaModule has 12 knobs that can be mapped to virtual knobs. Each knob can be mapped to up eight virtual knobs, and each mapping can have a different range and offset. You also can save a group of mappings as a Knob Set and switch between Knob Sets with the encoder. You also can map the 8 inputs and 8 outputs to virtual module jacks. Also, the MetaModule is a USB MIDI host, so you also can map MIDI CC, note, gate, and other parameters to knobs and jacks.ExpandersThere are lots of ways to customize your MetaModule. A Wifi expander allows you to wirelessly transfer patches from your computer. Add eight more knobs with the Knob expander, or buttons with the Button expander. A CV/Audio expander adds more high-resolution inputs and outputs, and the Gate In/Out expander adds not only gate jacks but also TRS MIDI and I2C.Under the HoodThere are six CV/Audio inputs, two gate inputs, and six CV/Audio outputs. The CV/Audio jacks are all 24-bit, 48kHz DC-coupled, -10V to +10V. A USB-C jack accepts MIDI devices and thumb drives. Patches and plugins can be loaded via a USB drive or microSD Card, and internal flash memory lets you save patches you always want to come back to.The processor is more advanced than anything 4ms has used in the past, and is among the most powerful processors found in Eurorack. Startup time and latency are blazingly fast.Features:Patches• Patches are loaded from microSD Card, USB drive, or via the Wifi expander• Patches can be optionally saved onto internal flash memory• Create patches using VCV Rack or directly on MetaModule• Patches can be given a name and descriptionMappings• Map each physical knob to up to 8 virtual knobs• Set range and offset for each mapping, including inverted control• Knob mappings are grouped into Knob Sets, and changing Knob Sets can be done quickly without menu-diving• Map physical jacks to virtual jacks, seamlessly making splits/mults• Add or edit modules, cables, and mappings in real-time while the patch is playing• Create alias names for mappings like "Kick Drum Level"Interface• Simple, intuitive graphical interface lets you zoom in on details, or zoom out to get a big picture• Patch View displays the patch as faceplates and cables, with knobs, buttons, and lights animating in real-time• Knob Set View simplifies the display, showing only the mapped knobs for the current Knob Set• Module View shows just one module and lists the names of each jack, knob, and control legibly• Mapping View lets you adjust details of a knob mapping• Adjust styles and visual preferences to your liking• Save, rename, duplicate, and delete patches• Firmware updater and plugin loader read from microSD Card or USB driveHardware• 12 Knobs• 8 CV/Audio outputs, 24-bit 48kHz, -10V to +10V, DC-coupled• 6 CV/Audio inputs, 24-bit 48kHz, -10V to +10V, DC-coupled• 2 Gate inputs• USB-C jack: MIDI Host or MSC (External drive) Host• microSD Card slot• Internal Flash RAM for additional patch storage• Dual-core 800MHz Cortex-A7 plus Cortex-M4 co-processor• 512MB DDR3 533MHz RAM• Bare-metal operation for fast startup and low latencyDIY-Kit-Type:Assembled unit.

Muxlicer is a sequential signal processor designed for add a huge range of special functions to your modular setup in the minimum space.Is divided in three main blocks: a Digital Step Controller, a Gate Generator and an Analog Switch (a.k.a. Mux/DeMux)The module is designed with high “function to HP ratio” philosophy , to have maximum flexibility in minimum space.An analog switch is a device capable of switching or routing analog signals. In the case of Muxlicer, the switch is reversible, so you can send 8 different signals to 1 destination and viceversa.Through Common I/O you can either send a signal to the Mux I/Os or receive a signal from them. (Depending on how the module is connected). It is also used as CV Out when nothing is connected to “All In” or “Mux I/Os”. The eight Mux I/Os are normalled to “All In” jack, so any signal present at this input will go to all of them.Imagine you want to send a signal to steps 1,2,4,5,6 and 8 and two more signals to 3 and 7 respectively. You just need three wires for this: plug the first one to All In and the other two to 3 and 7 Mux I/Os and you are done!Features:• Route any modular signal from one IN up to eight different Outs or vice versa.• Generate CV and Gate signals, been able to work as sequential voltage source a.k.a. sequencer.• Cut audio signals in rhythmical slices with independent volume.• Generate complex and dynamic patterns from any audio or modulation signal.• Create powerful Gate sequences with control voltage retriggering for each step.• Select easily when your signals act on your patch with the Address function.DIY-Kit-Type:THT-Kit-1.

Erica Synths - EDU DIY Drum Sequencer
available
Most drum sequencers are complex machines crowded with buttons and LEDs. The mki x es.edu DIY Drum Sequencer kit takes a different path: a hands-on rhythm engine with a minimalist interface built from just a handful of logic chips. The four independent channels are programmed in real time using a single button, so patterns loop automatically, can be shortened on the fly and support half-time playback for slower, evolving grooves.Accents and dynamics are handled by synced LFOs, and a simple resistor DAC converts patterns into stepped control voltages – perfect for modulating pitch, decay, filter cutoff, or other parameters. This logic-chip sequencer delivers tactile, musical performance without relying on microcontrollers, making it an excellent DIY drum sequencer kit for learning sequencer design and sharpening soldering skills.Features:• 4 independent channels with one-button step input/removal• 16 steps per channel, individually reducible to 12 or 7• Optional half-time mode per channel• Two syncable analog LFOs for dynamic accents• Resistor-DAC output for pitch or decay modulation• Internal clock with 16th, 8th, and quarter note outputs, syncable to external gearDIY-Kit-Type:THT-Kit-1.

If you’re new to DIY synthesizer building, you might’ve run into this issue: you just set up your first VCO on a breadboard, spent a good while troubleshooting the stubborn thing – and then you realize you have nothing to actually control it with. OR if you already have a decent modular setup, but still haven't found a simple, hands-on sequencer - here’s a compact, yet versatile 5 step sequencer with adjustable sequence length, per step gate status, and output range! It works both from an internal and external clock and has reset input for more complex sequences if several sequencers are chained up. It works also as a waveshaper when clocked at the audio rate.We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.In total, we have developed 9 kits to build a fully-featured modular monosynth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an Envelope generator, a dual VCA, and an output stereo mixer with a headphone amplifier. Additionally, an affordable eurorack case with a DIY PSU will also be available. While these kits are easy to build, we did not compromise on design and functionality. We will launch one kit every 4-6 weeks. For each kit, there is an extensive user manual (40+ pages; can be downloaded separately) that will dive deep into not only the electronics behind each circuit but also the fundamental principles of sound synthesis. We hope that the mki x es.EDU project will inspire future engineers and will contribute to the ever-growing diversity of electronic music technology.DIY-Kit-Type:THT-Kit-1.

Frequency Central - Polygraf
available
Polygraf is a step sequencer that features record/edit and playback functionality across 32 different patterns of up to 16 steps.Polygraf has four binary outputs (can be High or Low), labelled One, Two, Four, and Eight. During playback, Polygraf outputs a combination of High and Low for each of those outputs. The combinations can be edited by setting Polygraf to write mode and following the necessary procedure.Patterns: Polygraf has 30 Patterns (Patterns 1 to 30) that can be overwritten/edited, and 2 Patterns (Patterns 31and 32) that cannot be changed. Patterns are composed of up to 16 Steps (but can be recorded to be shorter).Steps: Polygraf has four binary outputs (can be High or Low), labelled One, Two, Four, and Eight. A Step outputsa specific combination of High/Low for each output. During playback, clocking advances Polygraf to the nextStep (or wraps around to Step 01 if there isn’t one). Individual output configuration can be uniquelyrepresented as a 0 to 15 number known as the State.State: A unique combination of On/Off for all of the outputs. There are 16 possible combinations thus 16possible States. We number these 00 to 15. A State’s identifying number can be determined by adding the valueof the outputs that are On. E.g. if outputs One and Four are On (and Two and Eight are Low) then the number is05 (because One + Four = 5).Pattern chaining: When in Play mode, Polygraf’s STATE potentiometer is used to determined the pattern chaining mode. Thepotentiometer acts as a four position switch. When changing between positions on the switch, Polygraf’s 7 segmentdisplays briefly indicate which position you are in, eg briefly showing ‘02’ to indicate the second position.DIY-Kit-Type:THT-Kit-1.

Music Thing Modular - Pulses (Turing Machine Expander)
sold out at the moment
Eleven rhythmic outputs for wONkY drum patterns.• Pulses turns the sequence from the main Turing Machine into a series of repeating rhythmic semi-random clock signals, that are based on the main clock input.• Seven of the 11 outputs are just the binary steps of the sequence on the front panel of the main module. The other four are derived from those pulses - so when steps 1+2 are active, the 1+2 output pulses.• As with most of the Turing Machine features, it is hard to explain, but very easy and intuitive in practice: send pulses from the module to anything that takes a rhythmic pulse; envelope generators, FM Index inputs, drum modules or other sequencers. Very complex polyrhythms come easily.• Because the Pulses are all related to the main module, they randomise, lock and change with that module. With the main module's big knob at 12 o'clock, the pulses are random. At 5 o'clock, they are locked, and at 3 o'clock they will 'slip' slowly over time.• You can try out a fully operational Turing Machine + Pulses + Volts in the free VCV Rack software.• Pulses connects around the back with a 16-way ribbon cable and works with any Turing Machine (Mk2, or Mk1 with the backpack).• Pulses uses Surface Mount components but is still a very simple build for anyone who has done a bit of through hole soldering beforehand.• Here is an epic series of videos from mixolydian2010 that documents the whole build process• Here's a very old audio demo from when I was developing Pulses, which shows the kind of polyrhythmic craziness it can create.• Despite involving SMD components, Pulses is a very straightforward DIY build, that most people complete without any problems.

Music Thing Modular - Turing Machine mk2

The Turing Machine is a binary sequencer based on a 16-bit shift register. Instead of precise programming, you steer its output.You can’t save or recall sequences—once changed, they’re gone.It generates clocked, stepped random control voltages (melodies, basslines, sequences) that can loop based on the length control.Since 2012, it’s been a popular Eurorack DIY project. Check #turingmachine on Instagram for demos.DivKid's 27-minute video explains it all, and here’s a 20-minute talk on its design.Sound on Sound Magazine published a nice review.Expanders connect to the module and modify sequences:• Volts: Extra voltage output controlled by five pots.• Pulses: Converts sequences into beats with 11 rhythmic outputs.• Voltages: Adds two CV outputs controlled by 8 faders.• Vactrol Mix: A matrix mixer for rhythmic audio cutting and panning.Looping is controlled by the big knob:• Noon = Random sequences.• 5 o’clock = Locked repeating sequence.• 7 o’clock = Double-length loop.• 3 or 9 o’clock = Loops with occasional changes.A free, virtual version exists in VCV Rack.Inspired by classic shift register synth circuits (Triadex Muse, Buchla 266, Noisering).Musically, it draws from 60s/70s minimalist composers like Steve Reich and Terry Riley.A Random Reading List covers its historical influences, from Marvin Minsky to Don Buchla.Open-source design has led to many clones and software versions (e.g., Mystic Circuits' Vert, VCV Rack modules, Mutable Instruments' Marbles).Despite the name, it’s not a true Turing Machine—just a looping data system.The original Mk1 documentation includes a detailed block diagram.It’s a dense but straightforward through-hole DIY build—better for experienced builders.

Music Thing Modular - Vactrol Mix (discontinued)
sold out at the moment
• Vactrol Mix combines four audio or CV signals into two channels, determined by the random sequence. It’s a great way to create stereo effects, complex waveforms or feedback loops.• This expander is 4 in, 2 out vactrol matrix mixer controlled by the Turing Machine, connected around the back by a 16 pin ribbon cable.• There are four inputs, for audio or CV sources. The four knobs set the level for each input. Next to each knob is a pair of LEDs. When the LED on the left is lit, the signal goes to the left output. When the LED on the right is lit, the signal goes to the right output. The LEDs are controlled by the Turing Machine module. The two outputs are both doubled (mult-ed) to make it easier to patch feedback loops.• Despite being less popular or widespread than Pulses or Volts, this is my favourite Turing Machine expander. It is a unique device that turns mundane source material into wild, unpredictable but rhythmically accessible patterns of sound. It’s a great way to create stereo effects, shifting drones, complex waveforms or feedback loops, and can be the heart of small (but chaotic) system.• Vactrols are electro-optical devices; a light shining on a light-dependent resistor. They have an extraordinary history, from powering the optical soundtracks on the first sound films in the 1920s to studio compressors, the tremolo in Fender guitar amps, and many of Don Buchla's 1970s synth designs. Modern vactrols are an LED pointing at a cadmium light dependent resistor, sealed together in a little black plastic box. Because the LDR reacts relatively slowly, the signals cut together smoothly, with no clicks or pops. Unfortunately, the cadmium in light dependent resistors is banned in Europe, so Vactrols are becoming harder to find.• Feedback is where this module gets really interesting. Try sending the (bottom) left and right outputs to your output mixer, and the (top) left and right outputs to spring reverbs or delays, patching the delay/reverb outputs back into input channels. Carefully ride the input levels, and you'll get snippets of feedback. The main clock speed can have a huge effect on feedback levels, because it takes a while to build up.• There are lots of Vactrol Mix audio examples in my Soundcloud: Twenty Minutes of Madness, Contact Mic Feedback and this ancient track recorded using the breadboard prototype.• The Vactrol Mix is DC coupled, so you can also rhythmically cut up DC sources; mix LFOs at different speeds with audio rate oscilllators, and frequency modulating a pair of oscillators using the two outputs.• This module was inspired by Grant Richter's Cadavre Exquis voltage controlled mixer, which was inspired by André Breton's surrealist game Exquisite Corpse. Richter's mixer also inspired the RxMx module by Make Noise.• Jonathan Higgins, on Facebook: 'There isn't a patch I don't use it on. People often thing you can only use it for crazy stereo percussion (which it is amazing at). But I also often patch all four outputs from the humpback filter into it for evolving stereo drones.'• The Vactrol Mix is a very straightforward through-hole DIY build.

sold out at the moment
• CV expander with 8 faders.• This is an eight stage random looping sequencer with illuminated faders, controlled by the main Turing Machine. Unusually, any number of stages can be active at once, creating unpredictable results.• It has two outputs, one normal – with a scale control that works in the same was as the similar control on the main module – and one inverted. The inverted output has a ‘shift’ control which raises (offsets) the voltage by up to 9 volts. This means you can drive positive-only modules (i.e. quantizers) with the inverted output.• In some ways, this module has been replaced by the smaller Volts expander, but some people still enjoy it. It's bigger and more tactile, and the two outputs interact in interesting ways.• Volts is a shrunken version of the original Voltages expander, and was designed in one day while on holiday in Cornwall.• This module is compatible with all versions of the Turing Machine. With the older Mki Turing Machine the Backpack module is also required.• Voltages is a very straightforward through-hole DIY build, that would be a good first DIY project.

Neutral Labs - Luna (Desktop)
available
This is the DIY Desktop version of this unit.Logic, Unbound. Meet Luna. The first serious Lunetta synthesizer.Look beyond clean waveforms and predictable polyphony. Luna takes you back to a time when digital didn’t mean perfect. It meant raw. Inspired by the subterranean DIY culture of the 70s and 80s, Luna is a love letter to the Lunetta machines of old – living, breathing organisms built from CMOS logic chips. But where those machines were fragile experiments, Luna is a weaponised instrument of sonic confusion.The Nervous System Exposed. True to the Neutral Labs philosophy, we don’t believe in hiding the magic behind an opaque faceplate. Luna features exposed CMOS inputs and outputs directly on the front panel. You're not simply patching cables – you are rewiring the brain of the synthesizer itself. Combine signals, bend logic, and physically intervene in the computation to create sounds that shouldn’t exist.Rhythm is Timbre. Timbre is Rhythm. In the world of Luna, there is no difference between a sequencer and an oscillator. The same digital pulse that drives a bass line can be accelerated into a screeching lead or folded into a metallic drone.Five oscillators provide the raw material. A chaotic array of logic blocks (XOR, NOT, AND, shift registers, counters, multiplexer) chews up those signals and spits out complex, evolving mathematical noise.Taming the Digital Mess. Raw logic can be harsh. To turn this binary chaos into music, Luna feeds its digital soul through three organic low-pass gates. These analogue circuits impart a natural decay and percussive punch to the madness, transforming mathematical errors into bongos, plucks, and thumping basslines.Drench it in Atmosphere. Once you’ve constructed your signal, destroy it again. Luna comes equipped with a suite of effects – distortion, delay, reverb, chorus, bitcrusher, phaser and more – to smear your logic into a wash of ambient bliss or gritty industrial texture.Features:• 5 oscillators• Logic gates (2 XOR, 2 NOT, 2 AND)• 5 logic blocks (5-step ring counter, 4-bit binary counter, 2 shift registers, 4-channel multiplexer)• 3 touchpads that generate logic signals• 3 channels for audio manipulation (low-pass gates with adjustable decay and switchable trigger mode, gain, tilt EQ)• 13 audio effects freely assignable to 2 effect slots running in series (drive, delay, reverb, 6 filter types, bitcrusher, phaser, chorus, comb filter)• CV control for effects and 2 oscillators• MIDI control over 2 oscillators, all 3 low-pass gates, and 3 logic outputs• 2 sequencers with up to 64 steps, syncable to clock or MIDI• Headphone-compatible audio outputDIY-Kit-Type:SMD-Kit-1.
