No samples, no DAW — every note is synthesised and chosen at run time by the program.
The picture below isn't an audio analysis: ChucK emits every note it plays, and the loom
weaves those exact events in sync. Pitch rises upward; each voice is a colour; the bright line is now.
Want to hear the language itself? The simulated ChucK runtime
interprets ChucK source live on Web Audio — strongly-timed code and sporked shreds, editable in the page.
