The Noise Swash is a chaotic random noise-maker and CV generator, generating its own sounds or working as an audio processor. As a stand-alone device it generates unpredictable continuously morphing oscillations on the Audio Output jack, and random CV fluctuations out the dual-direction "Mood CV" jack. A second CV input jack controls the Swash and Noisegate sections with positive and negative CV voltage. An audio input jack allows for distorting an audio signal beyond recognition, or using audio to trigger and modulate the chaos. The Swash knob is a 10-turn Bourns pot for adjusting minor variations. Each Swash has its own peculiarly unique sound.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module.

This is the last module in our T-Networks series, a straightforward 4 voice module with frequency and decay controls for each of the voices. As the name already unveils we added a noise source and created 2 different circuits that explore the timbre of a t-network when used to filter noise.There are 2 different circuits in this module: voices 1 to 3 have a pre-vca t-network filter while in voice 4 the t-networks filter applied post-vca.At each voice input there’s a switch that sets which type of input to use; this signal will be used to control an internal VCA hence why the type of setting defined here is important:1. Trigger - Any incoming CV will be converted into a 1ms trigger as soon as it crosses its fixed threshold.2. Mute - This disconnects then incoming signal effectivelly muting the voice.3. Envelopes - This can be used with CV sources as well as Gate sources and simply follows the input signal.This incoming signal will then be processed by a slew circuit which adds a decay factor allowing the user to set the “Tail” of each voice.Trigger mode is mostly dedicated for percussive sounds while the Envelope mode is open to any external envelope control and able to control noise swooshes, swirls, crackles and pops simply out of t-networks filtered noise.Audio inputs also welcome use as a Trigger/Envelope input, in fact the results of using this method had us all extremely surprised, so please do try it out!Diferences between voices:The first 3 voices also feature a Timbre selector switch: Hat/SnareIn Snare mode all frequencies coming from the t-networks filter pass through to the output .In Hat mode it adds a High Pass circuit which removes the mid/bottom frequencies (characteristic of the snare strike) creating a higher spectrum output which is closer to a Hat timbre.All of these 3 voices are also differently tuned from each other to offer more timbrical options.Voice 4 is closer to a typical t-networks circuit but this time a peculiar one where the noise is gated by the vca and then sent through the t-networks filter.Hat and Snare are terms used very loosely here; they are timbrical references and do not in any shape or form try to effectively replicate the complex timbres of a real world Hat or Snare.Features:4 Voices each with:• Frequency control• Decay control• Timbre type, Hat/Snare (Voice 1 to 3)• Frequency Range Switch, Low/Mod/High (Voice 4) Input• Audio Output• Also and overall Summing Mix output with Volume control and 2 diferent output types (Normal/Dirt)DIY-Kit-Type:SMD-Kit-2.

This new module should not be judged by its size, at 6hp it’s packed with features.At its core it features a noise source and two precision Sample & Holds that drastically reduce the typical voltage drop over time (20 minutes for a 0.01v drop) and with 0.3% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning.The Sample & Hold sections can also be used as a Track & Hold, meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.Each section also features its own slew processor with a single control over attack and decay and an ON/OFF switch.The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input, the sample and hold function will act upon the incoming noise signal, generating random CV values.The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.Besides each section outputs there are also 4 extra outputs: Noise, Difference, Average and Sum. The [Noise] output is coming from the noise source, the [Difference] output is the subtraction of section A minus section B, the [Average] output is the sum of both A plus B and then divided by 2 and finally the [Sum] output is the sum of both A plus B sections.DIY-Kit-Type:SMD-Kit-2.

cDVCA or class-D VCA is a new kind of VCA based on an entirely novel concept that is inspired from class-D amplification technology. This is not a transparent VCA and brings a lot of character to the sound.The first VCA that tracks 1V/octConcept: The input signal is turned into an ultrasonic PWM signal (~34kHz). The PWM is scaled to the desired amplitude and then filtered back down to the original signal.The twist: The PWM frequency can be lowered down into the audio spectrum and the frequency can be controlled via its 1V/oct input allowing for crazy waveshaping that tracks your melodies.The drive controls an innovative clipping method that does not rely on overdriving any circuitry and therefore results in distortions with a very defined character.The signal then goes into a 1 pole VCF/tone circuit that allows to keep things under some amount of control as the harmonics produced by this module can be very aggressive.With no input the module generates a simple square wave and therefore can be used a simple synth voice (VCO→VCA-VCF)DIY-Kit-Type:SMD-Kit-1.

Noise Plethora is a multitimbral noise monster in 14HP.The module consists of three digital sound generators, followed by three analog multimode Filters. This combination makes it easy to sculpt different textures and noises and play with them intuitively and musically.The first two channels let you choose from dozens of different algorithms and can be controlled dynamically by two CV controls.Textures, rumbles, low-fi blips, spikes, oscillator clusters, harsh noises, and much more can be chosen and changed on the fly.The third channel has three independent outs: Gritty noise to create crispy and crackling soundscapes, White noise, and a filtered version with either of those two.Features:• Two digital noise channels based on different algorithm banks• Two CV controlled parameters per algorithm• Analog Multimode Filter per channel (OTA based)• White and Granular Noise dedicated outputsed outputs.DIY-Kit-Type:THT-Kit-1.

Triple Bandpass Filters / Noise SourceDE-9 Box of Angels is a three stage bandpass filter/bandpass-gate with integrated noise source in 12HP. Box of Angels can be used as three serial filters, a bandpass gate/crude VCA, and as a separate gritty noise source. The noise source is normalled to the module input, which means that Box of Angels can be a sound source on its own. There is also a dedicated noise output if you want to use the noise with other modules in your rack. Each filter has its own Amplitude control with CV input and attenuator, as well as controls for filter frequency and resonance. Turing up the resonance on the filters and sending CV to each amplitude allows for some interesting evolving tones without the need for external input.DIY-Kit-Type:SMD-Kit-1.

No Input Feedback MixerShakti contains no less than 3 different feedback loops in a very small 4HP package. There are 2 internal loops represented by the pots FEEDBACK and FEEDBACK II.Where FEEDBACK is a normal signal, FEEDBACK II is an inverted signal and RECEIVE is an external path (one that you send out from the module, through any other modules of your choice and then back again).When working with feedback all three of these will intermingle fast which means both FEEDBACK pots and RECEIVE knobs will affect each other. A filter is attached to the first feedback path but since all signals will intermingle in this circuit (it is a mixer after all) the filter will affect all three paths.Starting with the knob in the middle, it has a lowpass filter to the right and high pass to the left. OUTPUT I contains the inverted signal whereas OUTPUT II contains the normal signal. Shakti can be used as a stereo module since the 2 outputs can differ drastically at times.!! WARNING !! DEALING WITH FEEDBACK CAN BE HAZARDOUS TO YOUR EARS AND GEAR SUCH AS OTHER MODULES, SPEAKERS, DAWS, MIXERS ETC. TO BE SURE YOU HAVE HEALTHY LEVELS ALWAYS PLACE AN ATTENUATOR OR ATTENUATED MIXER OUTPUT BETWEEN YOUR MODULAR AND OTHER GEAR.

Whether you use it for self-sequencing, for adding a dash of randomness to your filter movements, or for rough analog bitcrushing, a sample & hold-circuit can often be the secret sauce that takes your patch from decent to distinctive. That’s why we came up with this super simple JFET-based implementation – and then upgraded it with a couple of extra features like an internal clock generator or a dedicated slew output. Of course, we’ll need an interesting input to sample – which is why you’ll often find sample & hold modules with an integrated noise generator. So we’ll do the same! But instead of just one noise color, we’ll throw in two extra: pink and blue in addition to the standard white noise.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.

Chord Organ is the easiest way to get chords from a modular synth!• It's perfectly possible to create chords on a modular synth, but its a pain - lots of tuning and messing about. I wanted to create something as simple as a home organ with chord buttons. Chord Organ is exactly that; the top knob chooses a chord shape, the bottom a root note.• The full story of Chord Organ, including how it was inspired by a Bontempi Organ found in the street, is in this article over on Medium.• Chord Organ and Radio Music are identical modules; you can convert one to the other by installing new firmware over USB - details on how to install the firmware - and go back just as easily.• This video shows what you can do with a Chord Organ in a simple little case. Here the chord shape and root note are sequenced by an expanded Turing Machine and filtered through a God's Box Humpback Filter.• The top knob chooses the chord shape (Major, Minor, Drop 3 9th). The bottom knob chooses the root note. Both can be CV controlled.• The latest firmware now includes:• A choice of 12 waveforms (the original just had four) Program chords by uploading MIDI files Easy to use configuration page. Alternative tuning support by dropping standard Scala files onto the SD card (installation details).• There’s a long history of press-button-to-get-chord instruments; accordions, the Suzuki Omnichord, the Autoharp, or all those auto-accompaniment electronic keyboards that you used to see.Basically Chord Organ is a new firmware for the Music Thing Modular Radio Music module. It gives the module a completely different function. Instead of playing samples from the SD card, it synthesises chords. This is the full Chord Organ kit with dedicated Chord Organ silver Alu panel and button.Note: you need to purchase a MicroSD card and a Micro-B USB Cable elsewhere to set up this module. The Micro-B cables are the smallest type shipped with Kindles and many Android phones. You also need a card reader to write files to the SD card, many laptops and desktops already have them built in now. The very cheap $2 MicroSD cards are not worth the trouble they will cause you, buy genuine SanDisk or Kingston branded MicroSD cards from Amazon or elsewhere. 32Gb maximum… that’s 108 hours of lossless audio in 16bit 44.1khz. Total file limit per card is 1200 files.Features:For the build guide the process is identical to Radio Music, you just program with a different hex file – http://github.com/TomWhitwell/RadioMusicChord organ now tracks 1v/Oct if you use the latest software downloaded here! – http://polyfather.com/chord_organ/Details on how to load firmware onto the module can be found under the Software header here – https://github.com/TomWhitwell/RadioMusic/wiki/Preparing-the-TeensyDIY-Kit-Type:THT-Kit-1.

1) Magnetophon is a cassette player without the transport mechanism — a mono cassette head in the panel and a NAB equalised amplifier circuit, this is a tool for experiments with tape.2) Magnetophon is a tool for experiments with tape. Try rubbing old cassette tapes on the panel, or attach a head on a wire to recreate Nam June Paik’s Random Access or Laurie Anderson’s Tape-Bow Violin.3) NAB stands for National Association of Broadcasters. Their Reel-to-Reel Standard of 1965 specifies how tape heads should be amplified. If you plug a tape head into a microphone pre-amp, you get a very tinny sound with no low frequencies at all. Tape playback amplifiers (like the one in this module) boost bass by up to 10dB at 16Hz, while cutting highs by up to 20dB at 20kHz. Tape recorders apply the opposite curve when recording to tape.4) Don't expect a handheld cassette head rubbing against free-running tape to sound very hi-fi. It turns out all that head alignment and bias adjustment stuff wasn't BS after all.5) When experimenting with normal cassette tapes, a few things to remember: Stereo tapes carry four signal tracks; Left & Right Forward, and Left & Right Backward. So expect a bit of chaos.6) I've experimented with spoken word and language cassettes, forgetting that a decent proportion of them is just silence between words.7) If you have a reel-to-reel tape recorder, you can use an external tape head in a binder clip as a holder for tape loops. This will create a second output from the loop. It's likely to be MUCH lower fidelity than the main tape recorder output, but can sound really interesting mixed with the original signal (very Brian Eno tape loop-ish). Here's a quick demo of this technique from Brighton Modular Meet.8) The tape head inside the panel is fairly impractical for tape use, but can potentially be used for playing the magnetic strips on credit cards, MetroCards and the like. It will also pick up any electromagnetic noise and interference within your case (from switching power supplies, digital modules, colour-changing LEDs and the like).9) This is a fairly primitive and very high-gain circuit. In some situations, particularly when using the internal head, the circuit can oscillate. At audio frequencies this will sound like a whine. At frequencies above human hearing, it can just sound like silence, which drowns out whatever signals the tape head is trying to amplify. There is an empty spot for an extra capacitor on the PCB (C7). If you're having problems, try a small capacitor there; maybe 470pf, 1nf or more. Higher values will reduce the overall high frequency response. When using the external head, the capacitance of the cable seems to reduce the problem.10) This is a fairly simple build, but a rather exotic module.

Analog random voltage and noise generator in 3HP. It features sample/track and hold normalled to white noise with a toggle switch for selecting sample(switch right position) or track(switch left position) and hold function. There is also a PCB trimmer(at the top of the motherboard) to adjust the spread(gain) of random voltages out from “scalar” (low gain, counter clock wise) to large interval jumping(high gain, clock wise). All analog white, pink, and brown(red) noise 10vpp~(dependent on lower PCB trim). Smooth(infra red) random cv out at 10vpp with 2 range settings from wiggly with (more events, switch in left position) to almost random rise and fall envelope behavior (less events, switch in right position). White noise pcb trimmer sets the amplitude of the noise which in turn influences the rate of the infra out.

Analog random voltage and noise generator that expands upon the features of the Entropy Euroack Module in 3HPThe Entropy+Expander packs together some of the most random voltage options in 6hp. It provides a controllable “Glide”(slew) out for the S/T\H, a comparator with a controllable rate(“Thrsh”) of random gates(“Rand Gate”) out with an input to compare other waveforms(Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate “Blue noise”(+3db/octave) and “Violet noise”(+6db/octave) outs.The unique part of the circuit is a voltage controlled A/B switch thats normalled to the “Rand Gate” out that’s switching between the S/T\H out(left Blue led window)and Infra out(right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the “Entropy Out.” Inserting a cable into “Switch CV In” breaks the random gate normalization and lets you toggle between A/B(left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.There is a jumper on the pcb to select if you want glide on the s/t\h at, Entropy out, or un-slewed operation. There is also a trimmer for setting the amplitude of the incoming signal at “Comp In” which sets the frequency range of random gates. This may have to be adjusted depending on your Entropy version.The random gate range can also be set up more as a noise oscillator by turning the pcb trim(clockwise) up or it can be set so random gates are extremely slow(trim counter clockwise) with minutes between random gates.DIY-Kit-Type:THT-Kit-1.
