Ableton FX Chain

Ableton FX Chain

Build a tailored audio-effect chain on a track and dial in its key knobs — not just insert defaults. Genre character lives largely in the FX: lofi = saturation + bit/down-sample + low-pass + chorus wobble; dub = delay/echo + spring reverb; etc.

When to use

Triggers: "add effects", "lofi-ize / dub-ize", "process this track", "make it gritty/wide/warm". For designing an instrument's core tone use ableton-tone-recipes; for levels use ableton-quick-mix.

Process

1. Use ableton-live-runner for build/run/kill + scaffold + setParam.
2. Insert the chain in order with makeTrack's fxSlots (each slot a fallback list → one device

per slot). Order matters (e.g. EQ → comp → saturate → modulation → delay → reverb). End optional slots gracefully (a missing device is skipped).

1. Dial the key params with setParam (discover names at runtime; see ableton-tone-recipes):

filter cutoff, dry/wet, drive, feedback.

1. Verify by reading values back, and keep wet effects (reverb/delay) modest unless going dub.

Device names

Use the canonical confirmed/failed list in ableton-live-runner/references/gotchas.md (single source of truth — do not fork it). Common confirmed audio FX: EQ Eight, Compressor, Saturator, Overdrive, Redux, Vinyl Distortion, Auto Filter, Chorus-Ensemble, Reverb, Delay, Echo, Amp, Cabinet. (Auto Pan did not insert.) For any device not on the confirmed list (e.g. Glue Compressor), pass a fallback slot like ["Glue Compressor", "Compressor"] so the chain still builds if it is unavailable.

Genre chain presets

| Goal | Chain (left → right) | |---|---| | Lofi-ize | Saturator → Redux/Vinyl Distortion → Auto Filter (LP) → Chorus-Ensemble → Reverb | | Dub-ize | EQ Eight → Echo/Delay (high feedback) → Reverb (long) | | Clean guitar tone | Overdrive(light) → Amp → Cabinet → Chorus-Ensemble → Reverb | | Glue a bus | Compressor (or Glue Compressor w/ fallback) → EQ Eight → Saturator(gentle) | | Warm sub bass | Auto Filter(LP) → Compressor → Saturator |

Code pattern

const LOFI = [["Saturator"], ["Vinyl Distortion", "Redux"], ["Auto Filter"], ["Chorus-Ensemble"], ["Reverb"]];
const track = await makeTrack(song, "Keys", ["Electric", "Drift"], LOFI, notes, len);
await setParam(track, "Auto Filter", "Frequency", 3000); // muffle for lofi
await setParam(track, "Reverb", "Dry/Wet", 0.18);

Limits

• Param names/scales ("Frequency", "Dry/Wet", 0–1 vs Hz) differ per device/edition — discover them

at runtime (ableton-tone-recipes) before setParam; the values in the code are illustrative.

• Effects need an instrument before them to process; on an empty Drum Rack they process nothing until

a kit is dropped.

• No automation lanes — character must be a static setting (or implied by note dynamics).
