Model

ADDAC701 VCO

Portugal

The ADDAC701 is a fully analog voltage-controlled oscillator for Eurorack that produces four simultaneous waveform outputs - sine, triangle, sawtooth, and rectangular (pulse) - along with a mix section for blending them. It tracks 1V per octave pitch and has a linear FM input with adjustable depth, while the rectangular wave offers voltage control over its pulse width. The current REV2 version uses a CEM3340-based core for pitch tracking that stays stable across seven octaves.

Model

4ms Spectral Multiband Resonator

United States

The Spectral Multiband Resonator (SMR) is a 26 HP Eurorack module that processes audio through six resonant filter channels chosen from twenty tuned frequencies shown on its LED ring. It can work as a filter bank, vocoder, or struck-resonator, and quantizes its filter frequencies to selectable musical scales for harmonizing and remixing sound.

Model

2hp VCO

United States

The 2hp VCO is an analog voltage-controlled oscillator built around the reissued Curtis CEM3340 chip. It outputs triangle, sawtooth, and square waveforms simultaneously, with pulse-width modulation, linear FM, and hard sync. Accurate 1V/octave tracking across more than ten octaves suits both melodies and dramatic pitch sweeps.

Model

ADDAC508 Swell Physics

Portugal

The ADDAC508 Swell Physics is a Eurorack modulation source that simulates a small patch of open ocean, with four buoys floating on a wave surface generated by a Gerstner wave model. As the simulated water moves, each buoy rises and falls and reports its height to one of four CV outputs, producing slow, organic, fluid-like modulation. Controls over the wave parameters and the spacing of the buoys let the four outputs drift independently or move together.

Model

ADDAC112 VC Looper & Granular Processor

Portugal

The ADDAC112 VC Looper & Granular Processor is a stereo Eurorack module that pairs a real-time recording looper with a granular processing engine. Recorded loops are stored in a list so any sample can be recalled at any time, and the granular engine reshapes the selected loop with buffer sizes up to five minutes, ranging from subtle stutters to extreme transformation of incoming audio. Separate dry, looper, and grain volume controls feed the stereo output, and the module ships with a detachable patch panel that can be placed away from the controls.

Model

ADDAC104 VC T-Networks

Portugal

The ADDAC104 VC T-Networks is a four-voice Eurorack module built around Twin-T network circuits of the kind used in many classic drum machines. Each voice has a frequency control with a CV input and attenuverter plus a gate-to-trigger converter, so almost any signal can trigger its percussive resonant tones, and the four voices are combined through a summing mix output with volume control. Because of the gate-to-trigger circuit, audio fed into a voice input can also be used to create heavily destructive filtering effects.

Model

ADDAC306 VC Transitions

Portugal

The ADDAC306 VC Transitions is a five-channel CV generator that moves all of its outputs smoothly between voltage states. Each channel has its own minimum, span, and direction controls, and a single common slider morphs all five outputs at once between their minimum and maximum values. A common CV input lets an LFO, envelope, or sequencer automate the transition, making the module useful for large, coordinated parameter shifts from a single gesture.

Model

ADDAC207 Intuitive Quantizer

Portugal

The ADDAC207 Intuitive Quantizer is a four-voice Eurorack quantizer that snaps incoming control voltages to musical scales across a 10-octave range. It offers user-definable scales, several quantization modes, and a keyboard mode played from its buttons, and it can handle microtonal scales with more than 12 notes per octave alongside multiple temperaments. Tuning and up to 11 user presets are stored in non-volatile memory for recall.

Model

4ms Dual Looping Delay

United States

The Dual Looping Delay (DLD), designed by 4ms with Gary Hall, is a 20 HP Eurorack module with two delay and looping channels synchronized to a shared time base. It combines digital delay, looping, and sample-tight clock sync, with reverse playback, infinite hold, per-channel send and return, and up to roughly three minutes of delay or loop time per channel.

Model

2hp LFO

United States

The 2hp LFO is a voltage-controlled low-frequency oscillator offering eight waveforms with smooth morphing between them for complex modulation shapes. Its range spans from a thirty-second cycle up to audio rate. It provides two simultaneous outputs and a reset input for syncing to a clock.

Model

2hp Mix

United States

The 2hp Mix is a four-channel mixer for audio or control-voltage signals. Each of the four inputs has its own level control, and they are summed into a single output. It is DC-coupled, so it handles both audible signals and modulation with a low noise floor.

Model

4ms Quad Pingable LFO

United States

The Quad Pingable LFO (QPLFO) is a 12 HP Eurorack module with four independent low-frequency oscillators whose tempo can be tapped or clock-synced through a ping input. A skew control morphs each waveshape between pluck, ramp, and triangle forms, and the channels can modulate, trigger, and reset one another for evolving modulation.

Model

2hp ADSR

United States

The 2hp ADSR is a four-stage linear envelope generator with two selectable ranges. Its attack, decay, sustain, and release stages can each be adjusted independently to build simple or complex multi-segment envelopes. It is well suited to shaping filters, VCAs, and oscillators.

Model

4ms Stereo Triggered Sampler

United States

The Stereo Triggered Sampler (STS) is a 20 HP Eurorack module that records and plays back stereo WAV samples from a removable microSD card, with two files playable at once. It offers 1V/octave pitch control, CV control of sample selection, start point, and length, reverse and granular playback, and on-board recording and editing without a computer.

Model

4ms Ensemble Oscillator

United States

The Ensemble Oscillator (EnOsc) is a 16 HP Eurorack module built around sixteen sine oscillators that can be tuned together to chords, scales, or a harmonic series. It blends additive, frequency-modulation, phase-distortion, and wavefolding synthesis with mono or stereo output to explore the range between musical chords and evolving textures.

Model

2hp Euclid

United States

The 2hp Euclid is a rhythmic pattern generator based on the Euclidean algorithm, which spreads a chosen number of active steps as evenly as possible across a sequence. It produces repeating rhythmic patterns useful across many electronic music styles and offers voltage control over the pattern generation.

Model

4ms Pingable Envelope Generator

United States

The Pingable Envelope Generator (PEG) is a 20 HP Eurorack module with two envelope generators whose total time is set by a tapped or clocked ping, with each envelope running as a multiple or division of that ping from /8 to x8. Each channel offers CV control of shape and skew plus attack-decay, attack-release, cycling, and tap-tempo options.

Model

2hp TM

United States

The 2hp TM is a probabilistic random sequence generator inspired by the work of Alan Turing. Controls for randomness, sequence length, and output range let it act as a controlled random voltage source or, paired with a quantizer, an evolving melodic sequencer. Adjusting probability and length lets it produce a practically endless variety of patterns.
