Sources

Oscillators, noise, functions of time and samples. Every method works with no arguments.

Modulation

A parameter takes a number, another sound or a function of time, so one idea reaches pitch, cutoff, gain and mix, including FM.

Effects

Filters, envelopes, delay, reverb, modulation, distortion, pitch and stereo.

Notes and patterns

Sequences, scales, chords and a compact mini-notation, played by any instrument you describe.

Render or play live

Render to memory or WAV offline, or send the same sound to live output with slots you can swap while it plays.

Extend it

Write your own IOperator and use it like a built-in.
