TidalCycle / Superdirt

TidalCycles (or ‘tidal’ for short) is free/open source software, that allows you to make patterns with code, whether live coding music at algoraves or composing in the studio.

It includes language for describing flexible (e.g. polyphonic, polyrhythmic, generative) sequences. It also has an extensive library of patterning functions, for transforming and combining them.

Tidal is highly composable in that pattern transformations can be easily combined together, allowing you to quickly create complex patterns from simple ingredients.

Tidal does not make sound itself, but is designed for use with the featureful SuperDirt synth, and can control other synths over Open Sound Control or MIDI. Whether you’re using SuperDirt or a synth, every filter and effect can be patterned and manipulated independently with Tidal patterns.

Tidal is embedded in the Haskell language, although you don’t have to learn Haskell to learn Tidal – most tidal coders have little or no experience in software engineering.
