SuperCollider is an open-source object-orientated realtime audio synthesis programming language that runs efficiently across platforms. Below is some of my work for it in the form of classes and plugins.

I also have code published as quarks (AudioMulchClock, Bjorklund, Ease, PopUpTreeMenu, redGrain, redMst, redSampler, redSys, redUniverse, sInstruments, TraerPhysics, UGenPatterns) and here and here

SuperCollider ClassesπŸ”—


A hacked default synth. Note: this class will overwrite your default synth at recompile. Though it is easy to undo and get back to normal. See the accompanying help file for info. Used to be a quark.


Class for decoding mobile phone text messages (SMS).


Class for generating, parsing, manipulating and converting MaxMPSJitter patches.


A complete ft2 compatible tracker that can parse and play back .xm files (extended module).


A class that can parse and play back .mod files. Also works as a [glitch] tracker.


Deal with playing cards.


Class for formatting strings.


This utility class keeps track of documents in a folder. I use it like a quicklauncher.

external link version 050128.


Genetic algorithms. Breed synths in SuperCollider. Includes RedGAPhenome for translating an array of floats into a SynthDef.


Pattern class for 1D cellular automata.

Low-level code sharing.

SuperCollider Class ExtensionsπŸ”—


Extension for beatmatching, interpolation, synchronisation.

Previous versions:

(Version 3.6 and older include the macOS only RedInfo plugin for reading Apple's sudden motion sensor, ambient light sensors and battery capacity. Includes RedInfoBat, RedInfoLmu, RedInfoSms, RedInfoSms2, RedInfoSms3 as well as the RedAccelerometer wrapper classes.)


Old plugins. Bitwise calculations for SC synth (BitAnd, BitLeftShift, BitNot, BitOr, BitRightShift, BitUnsignedRightShift, BitXor).

Note: SuperCollider version 3.5 now has native support for bitwise operations on UGens, so you can use &, |, bitXor, >>, <<>. My bit plugins are only provided here for backwards compatibility. Do not use them for new projects!

Other SuperCollider WorkπŸ”—


A collection of instruments written in collaboration with Tamas Ungvary.

generated synthsπŸ”—

Synths generated using the RedGAPhenome class: n_noises and n_fmsynths.
More info and mp3 excerpts.

Synths generated by other means: n_fm7patches (req. Stefan Kersten's FM7 plugin from sc3-plugins.
