  RYO NOR/OR (Grayscale)   RYO NOR/OR boolean logic module euro, 4hp from ryo:  The NOR/OR module can be patched as two NOT gates, one NOT gate and one 2- or 3-input NOR/OR gate, one 2-input NOR/OR gate and one 2- or 3-input...

  The u1P is a Bernoulli gate. Based on the probability set by the potentiometer, it randomly routes a trigger or gate signal sensed at the input to either of its two outputs. Having three different operating modes (direct, toggle, single), it...

  One of Ray Wilson's most popular projects, now available as a DIY synth kit! Comes with the new version 17X7 panel. Find the original MFOS documentation here: MFOS Synth DIY Info   Features Two...

  This small utility is the pedal lover's best friend, it allows 2 diferent chains of pedals to be independently connected to your synth. The Send channels attenuate the synth level to instrument level. The Return channels amplify the signal...

  Scrat is an aggressive sounding multimode Steiner-Parker filter with a twist: You can change the resonance flavour by plugging in components like diodes, capacitors or resistors (even LEDs and/or light-dependent resistors) directly to the front...

  Beers 4013 Dual Flip-Flop HP eurorack module version of the classic 4013 CMOS IC. Two independent D-type flip-flops with SET, RESET, CLOCK, and DATA inputs and complementary outputs. On the rising edge of a signal applied to CLK the binary...

  Kassutronics Slope (Wood Panel)   Picture reflctes prototype panel not yet available The Slope module is a voltage controlled slew limiter and modulation source. The core idea behind this module comes form the classic Serge Dual Universal...

  Joystick replacement for the Transient 7J.

  NLC1127 Stochaos (White NLC) This module generates gates and control voltages based on pink noise or chaos or pink noise vs chaos. You can use a switch to select which variation. It uses a lot of cmos but I was careful to select chips that are...

  Beers 4047 VCO We are delighted to be offering these eurorack modules designed in Australia.  8HP, White Panel Isaac’s original VCO design, slightly cleaned up. This is an otherwise standard analogue triangle-core VCO design with a...

The CGS504 combines 2 functions in to a single module: Preamplifier - for scaling external audio signals to EuroSynth audio levels Envelope Detector - also known as an Envelope Follower and which extract amplitude information from complex audio...

  SSL Soleil Lo-Fi MIDI String Synth Pod The Soleil POD is a tiny low-cost Lo-Fi MIDI String Synth table-top box capable of playing 4 paraphonic notes. The unit includes the MIDI-TRS cable. Inspired by the early vintage string synths...

  PG-13 Passive Gates (S3 Series)   The PG-13 is so easy to build, even a kid could do it! (Adult supervision recommended). PG-13 is a simple, yet endlessly useful, passive dual gate with a tone control.(A pseudo-LPG, sorry no...

  manhattan analog dtm V1.2 DIY PCB Superceded by V1.3 The DTM is a discrete transistor circuit core mixer with 3 inputs and 1 output, based on the vintage Moog CP3. Very similar in features to Manhattan Analog's other mixer, the DTM...

  Custom enclosure for Ray’s Wilson’s Noise Toaster tabletop synth designed by synthCube. This aluminum enclosure features a speaker grill and predrilled holes for the power socket and battery clip. Hardware included. Ready to ship!

  Low-Gain Triangle VCO 4U   The Triangle Core VCO is a straight forward, stable basic VCO with 3 waveform outputs(Triangle, Sine, and Square). Expo/Lin FM Inputs, Sync, PW/PWM, & V/Oct (5-6 octaves). DETAILS Current: TBD ...

  Midi2TRS is a very simple but handy DIY kit. It does 2 things: • it converts the Midi-DIN input to 3,5mm TRS like it’s used now on many synths and controllers nowdays • it switches the polarity on the TRS side and by that flips...

  Low-Gain PVK Filter 4U   A classic programmable op-amp based Russian filter in a small package! Ping-able and gnarly! DETAILS DIY PCB 1 bipolar attenuated FM input 1 V/O fm input Current: TBD PCB Size:...

ADDAC System ADDAC 105 4 Voice Cluster Oscillator Following our ADDAC103 T-Networks this new module is inspired by its simplicity. This is a 4 voice Square Oscillator with VCA, FM switch and a slew decay for the incoming Trigger IN. All voices are then...

  Division 6 Dual Mini Sequencer   The Division 6 Dual Mini Sequencer gives you two handy little sequencers behind one Eurorack panel. Why would you need more than one sequencer? Why would you need mini sequencers? More sequencers = more...

  Frequency Central Tempograf Tempograf is a small 4HP clocking module derived from our popular Chronograf module. It takes some of the key features of Chronograf and presents them in a small form, but strips out some of the more advanced features...

  Erica Synths mki x es.EDU Output   The mki x es.edu Output Mixer is essentially a panning mixer – it takes two mono inputs with adjustable gain and pans them left or right to the stereo output, and an integrated amplifier boosts the...

  7dials Route 4 Sequential Switch Sequential switch module with binary address mode. This is a pcb + panel set only.  

  Kassutronics Wavefolder (Wood Panel)   Picture reflects prototype panel not yet available  This voltage controlled Wavefolder creates a rich spectrum of musical timbres, thanks to a smooth wavefolder core, integrated overdrive for added...

  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...
