Leaving the visible world behind, on purpose.
The Ensoniq DP/4 is a rack-mounted digital multi-effects processor. It uses four 24-bit DSPs to process four signals in parallel. Input gain is adjustable for saturation. Effects are intentionally non-realistic. Transformer noise occurs when idle. Front-panel editing is cumbersome. MIDI control via MIDIQuest is unreliable. The manual is unusable. An internal battery is user-replaceable.
The Buchla Music Easel is an analog synth with no technical specifications. That is all that is verified.
The Schrittmacher is a sequencer made by Manikin Electronic. No technical specifications are available. That is all that is known.
The Z.Vex Fuzz Factory is a 1995 fuzz pedal built around unstable germanium transistors whose biasing is manipulated via five interactive controls; it originated from Zachary Vex’s accidental discovery of extreme sonic behavior when boosting a surplus-transistor circuit, leading him to retain adjustable pots for expressive texture control rather than fixing component values.
Clouds is a granular audio processor for Eurorack that transforms live input into dense, overlapping grains. It records continuously into a short, variable buffer (up to 8 seconds), allows freezing that buffer to isolate a sonic space, and provides hands-on control over grain position, size, pitch, density, timing distribution, and envelope shape. A diffuser blurs transients using all-pass filters. It supports 40–60 concurrent grains and operates in stereo with extensive CV control, dry/wet blending, feedback, and reverb-like effects during freeze mode. It does not store or recall samples, nor does it support offline processing or waveform editing.
A compact, monophonic, fully analog synthesizer released in 2010 as a stand-alone version of the Doepfer A-111-5 Eurorack module. It features dual LFOs capable of audio-rate FM (~5 kHz), a 24 dB/octave low-pass VCF, and a triangle-based VCO. The VCF can function as a sine oscillator when the VCO is disengaged and resonance is maxed. All sound generation and modulation are analog; only USB/MIDI contain digital components. It has no polyphony, no patch memory, no velocity or aftertouch, and no audio input. Superseded by the Dark Energy II in 2012.
Mutable Instruments Marbles is a Eurorack module for generative timing and control voltage. It uses hardware randomness, memory-based reuse (DEJA VU), and adaptive quantization (STEPS) to produce rhythm and pitch that respond to player input. It has no audio output, no presets, no MIDI, and no visual interface beyond LEDs. Its strength is in linking decision-making across domains—timing, pitch, and memory—in real time.
MATHS is a 20hp Eurorack module by Make Noise Music that functions as an analog computer for generating, transforming, and routing control voltages and digital timing signals. It extends Buchla’s legacy of analog control voltage processing, enabling scaling, inversion, amplification, integration, arithmetic, logic, and autonomous function generation — including LFOs and envelopes — with timing ranging from milliseconds to minutes.
The Waldorf Microwave is a hybrid wavetable-analogue synthesizer whose distinctiveness comes from forcing digital waveforms through characterful analogue filters — not from flexibility, expansion, or modern workflow features.
René is a 34hp Eurorack module that functions as a three-channel, three-dimensional Cartesian sequencer, enabling real-time, performative programming and delivering maximal musical variation from minimal analog input; it stores up to 64 complete STATEs and features simultaneous Snake and Cartesian patterns, visual feedback via illuminated knobs and touch buttons, and Select Bus integration with TEMPI.
The Klon Centaur is an overdrive pedal introduced in 1994. It was designed to emulate high-volume amplifier distortion while preserving tone. Its circuit uses a JFET-based TL072 op amp and hard-clipping 1N34A diodes. After internal voltage doubling, the signal splits into three paths. It adds slight midrange emphasis. It was built as a standalone pedal in a custom-cast enclosure.
The Nord Modular is a 1997 software-based semi-modular synthesizer that uses DSP to emulate analogue circuitry and supports multiple synthesis methods including subtractive, additive, FM, and physical modelling. Patch editing is performed on a PC using graphical editor software, while sound generation occurs independently on the hardware. Patch complexity is constrained by available DSP resources, and polyphony varies from 4 to 32 voices depending on patch complexity. It was upgraded in 2004 as the Nord Modular G2 with endless rotary knobs and a larger keyboard with aftertouch.
The Serge synthesizer is an analogue modular system developed at CalArts in late 1972. It was built to be inexpensive and powerful, a democratic alternative to Buchla systems. It shipped as DIY kits assembled unofficially on a CalArts balcony. Modules expose circuit aspects on the front panel for unconventional patching. All signals use banana jacks—no separation between audio and control voltage. Stackable banana plugs reduce the need for mults. One unit was used on the 1975 Greenpeace anti-whaling expedition to approximate and broadcast whale sounds.
The EMS Synthi AKS is a portable modular analog synthesiser introduced in March 1972. It features a built-in keyboard and sequencer, a patch pin matrix, and shares design DNA with the VCS 3. Its sequencer creates eight-note repeating patterns. Users have described it as a 'noise machine'. One full album—Music from the SYNTHI—was made using only this instrument.
The EMS VCS 3 is a portable analogue synthesizer introduced in 1969 by Electronic Music Studios. Designed largely by David Cockerell and styled by Tristram Cary, it uses a pin-based patchboard matrix instead of cables. It lacks a built-in keyboard, making it better suited for sound effects generation and external signal processing than melodic playing. Its tuning instability stems from exponential voltage-to-frequency conversion. It was one of the first portable commercially available synthesizers, housed entirely in a small wooden case.
The Korg Wavestation is a vector and wavetable synthesizer introduced in 1990. It uses Wave Sequencing — a method of multi-timbral sound generation using successively played PCM waveforms — combined with Advanced Vector Synthesis, allowing dynamic mixing and morphing between up to four oscillators. It enables crossfading up to 255 waveforms, jumping to any PCM wave in ROM, and generating complex, evolving timbres and rhythmic sequences from a single keypress. Unlike contemporaries, it lacks an onboard sequencer and is designed as a 'pure' synthesizer.
The Fuzz Face is a minimal, high-character fuzz pedal built for affordability—not precision. Its two-knob interface and six-component design deliver immediate, touch-sensitive distortion, especially with NKT275 germanium transistors. But its crude biasing makes germanium units thermally unstable. Silicon versions trade warmth for harshness and reliability. It excels at organic, swelling fuzz tones shaped by the player—not the pedal.
