SuperCollider is anΒ open source object orientatedΒ realtime audio synthesis programming language that runs efficiently across platform. Below is some of my work for it in 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 sccode.org/fredrik-olofsson and here sccode.org/redFrik.

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.

download f0plugins for sc3.5 and earlier (272kb) (32/64 bit binaries for OSX, should work for sc 3.3 - 3.5)
download f0plugins_old_binaries (869kb) (binaries for OSX 10.5 and Windows)


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

download (89kb) (osx ub + win binary + source)

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!

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 here.

Synths genereted by other means: n_fm7patches (req. Stefan Kersten's FM7 plugin from SC3-plugins).
