| description | Good-to-knows from experienced Strudel / TidalCycles live coders — the high-leverage techniques that punch above their weight (scale-index melodies, chord+voicing, off() call-and-response, filter envelopes, detune-fatten, break-chopping) and the performance mindset (groove over complexity, embrace happy accidents, one motif many timbres). Use when a track feels amateur, you're hand-spelling notes the hard way, or you want the moves pros reach for first. Complements [[strudel-modifiers]] / [[strudel-effects]] (the full catalogs) with the *which-ones-actually-matter* shortlist. |
The vocabulary is huge ([[strudel-modifiers]] + [[strudel-effects]] catalog all of it). This is the shortlist pros reach for first — the moves that make the difference between "a pattern parsed" and "this sounds intentional."
The mindset (algorave wisdom)
- "A 4/4 kick beats 100 lines of clever code." (Alex McLean.) Groove and a strong hook win. Complexity that might break — or just muddies — loses. When in doubt, simplify.
- "The bug is part of the performance." (Renick Bell.) When a wrong note / accidental rhythm sounds good, keep it. The crank's whole spirit — happy accidents are gifts.
- One motif, many timbres. Don't write three melodies. Write one and restate it — on a bell, then a pad, then a lead an octave up. The carrier develops, not the tune. (Rone's signature.)
- Palette vs. canvas. Keep variations ready and bypassed, toggle them in. For us that's section files + keeping a voice's alt-version one edit away.
- Less, but moving. A spare line with a filter breathing under it beats a dense one that sits still. Movement > note count.
High-leverage techniques (use these constantly)
- Scale-index melodies — never hit a wrong note. Write degrees, not pitches:
n("0 2 4 2 0 -3").scale("C:minor"). Stays in key automatically; transpose the whole line by changing the scale ("C:dorian", "Eb:major"). This is the fastest way to a clean, in-key hook — and the easy fix when a hummed melody has stray notes.
- Chords from symbols + auto-voicing. Don't hand-spell every chord tone:
chord("<Cm Ab Eb Bb>").voicing() voices them with smooth voice-leading. .voicing("above:c3") to set the register.
- Arpeggiate a chord.
chord("<Cm Ab>").arp("up down") (or .arp("<0 2 1>")) turns a chord into motion — the David-Wise "the arp IS the pad" move, for free.
- Call-and-response in one line.
.off(1/8, x => x.add(note(7)).gain(.5)) plays a quieter copy an 8th late, a 5th up — instant Bonobo answer-phrase without writing a second voice.
- Filter envelopes = the "expensive synth" pluck. Static
lpf is flat. .lpf(800).lpa(.1).lpd(.2).lpenv(4) makes the cutoff move per note (attack lpa, decay lpd, depth lpenv). This is what makes a saw sound played, not held.
- Fatten anything with detune.
.add(note("0,.07")) stacks a slightly-detuned copy → instant chorus/supersaw width. .add(note(perlin.range(0,.4))) = drifting tape-warble.
- Humanize with probability.
.sometimesBy(.3, x => x.speed(2)), .rarely(ply(2)), .someCyclesBy(.25, x => x.crush(4)) — small odds of a variation keep loops from feeling robotic.
- Chop the breaks (we load the amen + crate):
s("amen").fit().chop(16) slices a break to the tempo; .slice(8, "<0 1 2 3 4*2 5 [6 7]>") reorders the slices — jungle/DnB from one sample.
run(N) walks a bank. n(run(8)).s("mridangam") plays samples 0–7 in order — fast way to audition or sequence a kit.
The mental model (why Strudel feels different)
- A pattern fills ONE cycle, always.
s("bd sd hh") = three events evenly across the cycle; add a fourth and they compress to fit. Time is relative, not a timeline. This is why you layer by stacking patterns of different densities, not by counting beats.
setcps, not BPM. cycles/sec. setcps(0.5) ≈ 120 BPM in 4/4 (one cycle = one bar of 4 beats → 0.5 cyc/s × 4 = 2 beats/s = 120 bpm). setcpm(120/4) is the readable equivalent.$: labels (strudel.cc REPL) let you name + mute/solo voices live. In our file-based tracks, that's what the stack(...) voices + section files do.
Where the rest lives
- Full method catalog → [[strudel-modifiers]]; every filter/effect → [[strudel-effects]]; the "weird" toolbox → [[strudel-weird]].
- Every instrument (incl. the 128 GM voices) → [[strudel-sample-library]].
- Live-performing the edits → [[strudel-conduct]].
