Eurorack Modules

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.

Make Noise DPO

Eurorack module · United States

The Make Noise DPO (Dual Prismatic Oscillator) is an all-analog complex oscillator Eurorack module built from two voltage-controlled oscillators designed for generating complex, harmonically rich waveforms, with hard sync, dedicated FM and modulation buses, and extensive waveshaping.

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.

After Later Audio Monsoon

United States

A Eurorack texture synthesizer and granular processor by After Later Audio, adapting the Mutable Instruments Clouds design with the expanded Parasites firmware into a compact panel. It captures and granulates incoming audio for ambient textures, pitch shifting, and time stretching.

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.

Expert Sleepers Disting mk4

United Kingdom

The Expert Sleepers Disting mk4 is a version of the multifunction Disting Eurorack module, offering an expanded set of algorithms and improved interface and storage while keeping the compact, do-many-things design.

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.

AJH Synth MiniMod Discrete Cascaded VCA

United Kingdom

A Eurorack discrete voltage-controlled amplifier by AJH Synth, part of the MiniMod series, built from a discrete transistor cascade to reproduce the gain character of the original Minimoog output stage. It offers both linear and exponential response modes.

After Later Audio Cara

United States

A Eurorack random voltage and CV source by After Later Audio, a compact adaptation of the Mutable Instruments Marbles design (also sold as uMarbles). It generates clocked random gates and continuous control voltages with controllable rate, spread, and bias for generative patches.

Make Noise Maths 2013 Revision

A major revision of the Make Noise Maths Eurorack module.

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.

Mutable Instruments Beads

Eurorack module · France

Mutable Instruments Beads is a texture synthesizer Eurorack module and the successor to Clouds, combining granular synthesis with audio recording and processing in a refined 14 HP design. Like all Mutable Instruments products it is open-source hardware and firmware; the company ceased operations in 2022.
