Strudel Cheat Sheet

Strudel is TidalCycles ported to JavaScript, running at strudel.cc with no install. Same mini-notation, method-chaining instead of Haskell operators.

Play

sound("bd sn hh sn")Play a drum pattern

note("c e g").sound("piano")Play notes through a sound

n("0 2 4").scale("C:minor").sound("triangle")Scale degrees into a synth

silenceAn empty pattern

$: sound("bd*4")Name a running pattern (REPL)

"bd sn hh cp"Sequence across the cycle

"bd*2"Twice as fast

"[bd sn]"Grouped into one step

"bd(3,8)"Euclidean rhythm

"<bd sn>"Alternate each cycle

"bd:3"Sample index

"~"Rest

.fast(2).slow(2) — change tempo of the pattern

.rev()Reverse each cycle

.every(4, x=>x.fast(2))Every 4th cycle, transform

.jux(rev)Stereo split with a transform on the right

.off(0.125, x=>x.add(7))Echo a shifted copy

stack(a, b)Layer patterns

cat(a, b)One per cycle in turn

.gain(0.8)Level

.lpf(800).hpf(200) — filters

.room(0.5)Reverb

.delay(0.5)Delay send

.pan(0.3)Stereo pan

.crush(4)Bit-crush

.speed(2)Sample speed / pitch

setcps(0.5)Cycles per second (tempo)
