Ableton Genre Cover

Ableton Genre Cover

Turn a known theme/song into a full, playable arrangement in a target genre, written directly into a Live Set as separate MIDI tracks (drums, bass, harmony, lead, texture) with fitting instruments and FX chains.

When to use

Triggers: "make a reggae version of the X-Files theme", "lofi cover of Smells Like Teen Spirit", "turn this into dub", "[song] but [genre]". For reharmonizing an existing clip use ableton-reharmonize; for just a bassline/melody/drums use the dedicated skills.

Process

1. Use ableton-live-runner for the build/run/kill workflow and the scaffold helpers. All code

below goes in the scaffold's compose().

1. Get the source theme accurate. The recognizable melody is what sells a cover — verify it (web

search a transcription / sheet music / letter-note tab) rather than guessing. Capture: key, tempo, time signature, the main melodic motif (as {t, p, d} events — time/pitch/duration in beats, matching the code below), and the chord/root progression. A wrong melody ruins the cover; spend the lookup.

1. Decide the genre treatment (ask the user 1–2 focused questions if ambiguous — e.g. sub-style,

tempo). Map the original harmony onto the genre's rhythmic feel; keep the identity markers (signature riff, characteristic intervals, the turnaround) and change the rhythmic clothing.

1. Write the tracks with makeTrack, gated into sections with inRanges:

• Drums (Drum Rack, empty → user drags a kit): the genre's groove (one-drop, boom-bap,

four-on-the-floor…).

• Bass: roots of the progression in the genre's rhythm (leave space on 2 & 4 for reggae; deep

sub + syncopation for lofi).

• Harmony: skank chops on the off-beats (reggae/ska), or sustained reharmonized chords (lofi).
• Lead: the source melody, transposed to a fitting register.
• Optional pad / counter-line / arpeggio for the identity hook.

1. Pick instruments + FX per role (see ableton-fx-chain and ableton-tone-recipes). End every

instrument list with "Drift".

1. Build, run, diagnose per ableton-live-runner. Remind the user to drop a drum kit and hit

Play.

Genre starter map

| Genre | Tempo | Drums | Harmony feel | Bass | |---|---|---|---|---| | Roots reggae / one-drop | 70–80 | kick+snare on beat 3 | organ skank on off-beats | round, syncopated, spacious | | Ska / rocksteady | 95–110 | backbeat 2 & 4, open-hat off-beats | short guitar chop on every "&" | bouncy, walking | | Dub | 65–75 | sparse, drops | rare, drenched in reverb/delay | HUGE, up front | | Lofi hip-hop | 70–85 | boom-bap, swung hats, dragged snare | reharmonized 7/9 chords on Rhodes | deep sub, sparse |

Code pattern (section gating + theme statement)

const THEME = [ { t: 0, p: 81, d: 3 }, /* the verified motif, clip-local beats */ ];
function writeLead(notes, startBars, beatsPerBar) {
  for (const startBar of startBars)
    for (const e of THEME)
      notes.push({ pitch: e.p, startTime: startBar * beatsPerBar + e.t, duration: e.d, velocity: vary(100) });
}
// Harmony as off-beat skank:
for (const off of [0.5, 1.5, 2.5, 3.5])
  chord.forEach(p => notes.push({ pitch: p, startTime: b + off, duration: 0.12, velocity: vary(90) }));

Limits

• Drum Rack loads empty — the user must drag a kit. Note this every time.
• Keep each cover in its own Set (global tempo). Make re-runs idempotent via clearPriorTracks and

per-cover TRACK_NAMES.
