Chaosynth is a software synthesiser which uses cellular automata and granular synthesis to create a new sound set for the electronic musician. It can be used as a one-shot sample generator with direct to disk recording, or it can be driven by MIDI as a fully functioning monosynth.

Cellular automata is the primary guide to the timbre of sound generated by Chaosynth. It consist of a group of cells that evolve over time following a pre-defined rule. At each time segment, every cell changes its state depending on the conditions of its neighbors. Starting with a random state, the cellular automata quickly settle to form organic and eventually oscillating patterns. When this is translated into sound, a complex evolving waveform is formed with a rich texture.

Chaosynth combines cellular automata with granular synthesis to produce a much more distant, controllable and varied sound than traditional granular synthesisers. This combination of cellular automata and granule synthesis is a first of its kind. The sounds produced include ambient, strange and effects based styles amongst others.

Purchase Information

  • ~$40


  • Windows 95/98/NT 4.0 or higher
  • Pentium or better (Pentium 200 MHz recommended)
  • 16-bit sound card or better
  • Microsoft DirectX 6.0 or higher for DirectX support

Note that there are two versions of the program. One for Windows 95/98 and the other for Windows NT. Make sure to download the correct version for your system.



The demo version has the following restrictions:

  • Main Panel – Output fixed to 22 kHz, 16-bit, mono WAV files using a sine waveform
  • Frequencies – Fixed number to 16
  • Oscillators – Fixed number to 8
  • Size – Fixed to 100 granules and no option to fix length
  • Cellular Automata settings – Totally disabled
  • Envelope – Totally disabled
  • Reverb – Can only use default settings (active toggle is only active control)
  • Filters – Limited to low-pass
  • Modulation – Type and waveform controls disabled. Limits to single/single modulation of sine wave

Restricted features can still be demonstrated by loading the example CSP files included with the demo.
