Swync

Live: change the code, hear it immediately

Musical: work with time signatures, bars, and western note values and pitches

Patterns: lists you can visualize

Arrange: create arrangments through a rich set of pattern chains play/playn/then/then_after

Stochastic form: random choice at a structural level

Rust-like simplicity: let, fn, use, for, ranges, blocks. Synths are functions
