The FMP is an 8 HP Eurorack FM synthesizer module built around the classic Yamaha YM2413 chip, known for its distinctive sound in vintage game consoles like the MSX, Atari, and Sega systems. Capable of producing everything from clean tones, deep kicks, and noisy snares to bell-like textures and even polyphonic chords, the FMP offers two modes: Tone mode provides a 2-operator FM voice with self-modulating feedback, while Drum mode exposes the chip’s built-in percussion sounds with adjustable levels and pitch. Seven parameters shape the sound and CV interpolation between two parameter sets enables evolving, expressive patterns. While inherently lo-fi, the FMP embraces this character to deliver dynamic, gritty textures, with settings that can be saved for consistent recall. Its charm lies in the unpredictability, offering a rich playground.Features:• 8 HP FM synth voice based on Yamaha YM2413 chip• Two modes: Tone (2-operator FM synth) & Drum (built-in percussion sounds)• Wide sonic range: kicks, snares, hats, bells, chords, and more• Seven tweakable FM parameters• Save and recall settings on power-up• Characterful lo-fi sound with modulator feedback• Adjustable pitch and mix levels in Drum mode• Inspired by classic game console sound chips (MSX, Sega, Atari)DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder.

The SDSV+ is a Eurorack drum voice inspired by SyntherJack’s SDSV project and the iconic Simmons SDS5/SDSV drum machine. This enhanced version goes beyond the original by offering expanded sound-shaping capabilities and increased CV control, making it ideal for crafting everything from classic toms, snares, and kicks to hi-hat, crash, and FM-style metallic sounds. If you want to create vintage punch or experimental textures, the SDSV+ delivers dynamic percussion with modular flexibility.Features:• Envelope selection for the VCO and separate Decay pots• Option to use unfiltered noise for click (and the option to turn click off altogether)• Redesigned one of the envelopes to make it independent of input trigger length.• More CV inputs• Noise level controlDIY-Kit-Type:SMD-Kit-1.

Basilisk is a new bass-line exploration synthesizer from Wirehead Instruments, with dual digital oscillators driven into an aggressive MS20-style analog filter coupled with a powerful generative sequencer.Whether you need thumping bass-lines, melodic leads, or percussive tribal beats, the Basilisk is ready to lead you down the rabbit hole from the moment you power it on.The dual oscillators include saw and square/pulsewave, with manual & LFO control over PWM, detune, pitch envelope & glide.The analog filter has a fat saturated drive stage with resonance that can go from subtle to squelching to screaming, and the external audio input can process instruments from your desktop or EurorackAll of this can be sequenced and modulated by the attack/decay exponential envelope, multi-waveform/multi-destination LFO and Elektron-style parameter-locks.The Basilisk is powered by a 1-16-step generative sequencer evolved from the Freaq FM, with multiple algorithms. Explore deep space, underground caverns, deep jungle or 1980s suburbia!Features:Oscillators• 2 digital oscillators - saw, square & pulse• De-tune control that always stays musical, from light flanger to rich chorus, dial it up for fat fifths and octavesAnalog Filter• MS20-style 12dB resonant multi-mode filter• Analog filter drive from -20dB to +20dB saturated overdrive• Low-pass and non-resonant high-pass mode• Digitally-controlled cuttoff modulation• External audio input accepting wide range of signals from 1v p-p to 10vp-pModulation• Attack/Decay envelope with shape control, routable to filter cutoff and/or pitch• LFO with multiple waveforms and configurable destination: cutoff, envelope (attack, decay or depth), note • length, PWM, detune, octave or sequence length• 6 modulation lanes with full 16-step parameter-lock recording of synth parametersGenerative Sequencer• Generative sequencer with 1-16 steps• Multiple generative algorithms including scale-notes, runs, scale-arpeggio, call/response• Sequence mutates/evolves at user-defined rate & note-density• Selectable tonic, octave & scale• Tap-tempo control• Analog sync input & output (Volca, PO or Eurorack compatible with 1/2/4 steps per pulse)Patch Memory• Persistent patch memory saving all digital synth and sequence parametersHardware• Mono audio output (32KHz 14-bit DAC, 4v p-p)• Sync input / output (0-5V rising-edge) • Audio Input (1v p-p to 10vp-p)• Powered by an Arduino Nano V3!• 142m (w) x 100mm (d) x 40mm (h)• 9-12V DC or micro USB powered (70mA @ 12VDC)DIY-Kit-Type:THT-Kit-1.

The Trepanator is a 14 HP analog “Bent by Design” experimental instrument featuring a Dual VCO, Difference Rectifier, 3-band EQ, Sample/Track and Hold, and SVF (state variable filter) all built into one nonlinear module. Its origins trace back to a love for Rob Hordijk’s Benjolin and patching a similar pseudo chaotic feedback-based instrument from scratch using all Zlob modules.Although not based on Hordijk’s circuit or signal flow, it uses a similar architecture of dual voltage controlled oscillators, an “interference pattern generator,” a state variable filter, and internalized cross-patched feedback. Instead of a Rungler and comparator the Trepanator uses a sample/track and hold with slew, a difference/rectifier circuit (based on NLC), and a self-oscillating 3-band EQ. Utilizing this excessive feedback between the VCO’s, EQ, S/H, and SVF, creates a completely new instrument for discovering abstract electronic sounds. The Trepanator is a highly interactive, unpredictable, and an immediate instrument capable of a huge range of organic and sounds from: snarling, plucking, bubbling, screaming, gurgling, hissing, grunting, pinging, and quacking, to machine like rhythmic loops, circuit bent broken modem sounds, no-input mixer screeching, intermittent short wave radio fizzling, and full on Harsh Noise Wall all within the touch of a fader or a small knob turn without any external audio or any control voltage in.Double Sided PCB panel with Classic and Soulless.For more info consult the manual below and signal flow chart.RIP Rob HordijkDIY-Kit-Type:THT-Kit-1.
