Write Strudel code to a file and trigger the REPL to evaluate it. Use when composing or modifying music patterns for live playback.
Clone Strudel repo, install dependencies, and start the dev server. Use when setting up the project for the first time.

| description | Strudel mini-notation and pattern quick reference. Use when writing or explaining music patterns. |
Mini-notation is the string DSL inside double quotes. One cycle = one musical loop.
| Syntax | Meaning | Example |
|---|---|---|
"a b c" | Sequence (evenly spaced in cycle) | "c3 e3 g3" = 3 notes per cycle |
"[a b]" | Group (subdivide) | "c3 [e3 g3]" = c3 half, e3+g3 quarter each |
"a*N" | Repeat N times | "hh*8" = 8 hi-hats per cycle |
"a/N" | Slow down by N | "bd/2" = bass drum every 2 cycles |
"a?" | Random removal (50%) | "hh?" = sometimes plays, sometimes silent |
"a b , c d" | Stack (overlay/polyrhythm) | "bd sd , hh*4" = drums + hi-hat layer |
"<a b c>" | Alternate per cycle | "<c3 e3 g3>" = different note each cycle |
"a!N" | Replicate (same timing) | "c3!3" = c3 three times at same speed |
"~" | Rest (silence) | "bd ~ sd ~" = kick, rest, snare, rest |
// Basic sounds
sound("bd sd hh sd") // drum pattern
note("c3 e3 g3 b3") // melodic pattern
// Modifiers
.fast(2) // double speed
.slow(2) // half speed
.rev() // reverse pattern
.jux(rev) // stereo: original left, reversed right
.every(4, fast(2)) // every 4th cycle, double speed
// Effects
.cutoff(1000) // low-pass filter at 1000Hz
.resonance(10) // filter resonance
.delay(0.5) // delay effect
.room(0.8) // reverb
.gain(0.7) // volume
// Scales & chords
.scale("C:minor") // map to C minor scale
n("0 2 4 6").scale("C:minor") // scale degree pattern
// Stacking
stack(
sound("bd sd"),
note("c3 e3 g3").sound("sawtooth")
)
Simple beat:
sound("bd sd:1 hh sd:2").bank("RolandTR808")
Ambient pad:
note("<c3 eb3 g3 bb3>")
.sound("sawtooth")
.cutoff(800)
.room(0.9)
.slow(2)
Layered groove:
stack(
sound("bd*2 [~ bd] ~ bd").bank("RolandTR808"),
sound("~ sd ~ sd:1").bank("RolandTR808"),
sound("hh*8").gain(0.4),
note("c2 [~ c2] eb2 [~ g1]").sound("sawtooth").cutoff(400)
)
When explaining patterns to the user, always describe the audible effect — e.g., "this creates a syncopated kick pattern with a filter sweep."
