SignalFunctionSet
Plugins for VCV Rack and the Critter & Guitari EYESY, desktop software for samplers and synths, and workshops on synthesis and sound design.
VCV Rack
Free, open-source modules for VCV Rack. Most also run on the 4ms MetaModule.
Flock In
An expander for the Flock granular voice in VCV Rack. Patch audio in and the birds sing grains of it instead of sines, with envelope, reach and freeze controls.
Flock
A microtonal granular voice for VCV Rack built on a real flock. Up to a thousand birds fly as a murmuration, every call is a grain, and height in the flock is pitch.
Field
A random voltage source for VCV Rack. Nineteen jacks on a hexagonal grid read one smooth random field, so neighbouring outputs are related by geometry.
PolyKit In
An expander for Kit in VCV Rack. Every input of every instrument as its own jack, thirteen columns by eight rows, for racks patched from eight sources rather than one poly cable.
Spool
A tape instrument for VCV Rack after the Mellotron. Four short tapes played by gates, with varispeed pitch, and a tape that never rewinds when you stop.
EYESY
Visual modes for the Critter & Guitari EYESY video synthesizer.
Image Trip
An EYESY video synth mode that transforms static images into flowing kaleidoscopic animations by stretching and repeating rows and columns of pixels.
String Vibrations
An EYESY video synth mode that renders incoming audio as a scrolling 3D field of vibrating strings. Each string shows the waveform at a different moment in time.
Cubicles
An EYESY video synth mode: a 3D wireframe cube matrix with depth-of-field effects that pulses with brightness and color highlights in response to audio.
Tempestuous
An EYESY video synth mode inspired by classic vector arcade games: fly through a 3D tunnel that warps and pulses in response to incoming audio.
Software
Desktop tools that make working with samplers and synths less painful.
SampleStack
A desktop sample manager for Eurorack and hardware samplers. Organize, browse, convert formats, and transfer sample libraries without the painful CLI workflow.
WaveStack
A desktop wavetable builder. Draw and shape single cycles, sweep a whole table from keyframes, import Serum and Surge tables, and export in the format your synth or module expects.
EYESY Simulator
A free native macOS and Windows simulator for the Critter & Guitari EYESY video synthesizer. Develop, test, and preview video synth modes without the hardware.
Workshops
Slide decks and materials from workshops on synthesis and sound design.
Intro to Synthesis
An interactive workshop on the fundamentals of subtractive synthesis. Build a classic synthesizer voice in VCV Rack from oscillator to VCA, then take it apart, with live Web Audio on every slide.
Granular Synthesis Workshop
Workshop materials on granular synthesis: interactive timeline, curated mixtape, and historical notes from Fourier to Mutable Instruments. Run at Synth Library Portland.
Writing
Notes and essays on synth tool design, workflow, and the practice of building instruments.
