Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.02237 |
| Opus 5.5 | $0.00023 | $0.00895 |
| Sonnet 5.5 | $0.00011 | $0.00447 |
| Haiku 4.5 | $0.00006 | $0.00224 |
Grade A, and why
ableton-arrangement scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ableton Arrangement — composing full songs via MCP
Song-agnostic patterns for fleshing a song idea (MIDI or chart in hand) into a full
arrangement. Validated on a hardcore-punk 11/4 reinterpretation of a Byzantine hymn;
applies to any genre/key/meter. Connection mechanics and device gotchas live in the
ableton-mcp skill; analysis of existing recordings in song-analysis.
Track layout template
Works for rock/punk/electronic/cinematic reinterpretation:
| Track | Role |
|---|---|
| Reference (muted) | Original melody/reference audio for A/B |
| Melody / Voices | Lead vocal or chant melody MIDI |
| Bass | e.g. Deep Hop Bass rack, Electric Basic Bass, String Studio |
| Rhythm Guitar | Power chords — Guitar-Dual Amped Heavy (heavy) / Crunch (medium) |
| Drums | Kit (Memphis Studio etc.) — kick=36, snare=38, hh_closed=42, hh_open=46, crash=49, ride=51, toms=41/43/45 |
| Lead Guitar | Same guitar rack as rhythm, Amp Gain pushed (~115/127) |
| Color/Aux | Trumpet, strings, pads — punctuates bridges, fills holes |
One MIDI clip per track at song length (e.g. 198 beats for 18 bars of 11/4). Slot 8 is a good "live" slot; leave slots 0–7 for variations.
Section design
At least 5 sections, each with its own character:
| Section | Bars (typical) | Function |
|---|---|---|
| Intro | 1–2 | Bass + lead color only. No rhythm guitar. Anticipation. |
| Verse build | 3–4 | Rhythm guitar enters. Bass still sparse. |
| Chorus | 5–8 | Full instrumentation, peak energy. |
| Bridge | 9–12 | Pull back — sparse; a NEW instrument enters (trumpet, strings). Lead silent. |
| Solo | 13–16 | Lead foreground. Drums change pattern (ride > closed hat). |
| Outro | 17–18 | Breath, then finale hit. |
Each instrument changes role per section — never the same density throughout. The contrasts create the song's narrative.
Dynamic techniques (proven to add soul)
- Pre-section drops — silence drums + bass for 1 beat before each section change. The ear reaches for the missing beat → next section HITS harder.
- Section-based volume automation via
set_clip_automation"Volume": Intro 0.65, Build 0.85, Bridge 0.70–0.78, Solo 0.95, Outro 0.70 → 1.0. ⚠️ Only works where the track exposes Volume as automatable — bass usually does; drum kit racks and guitar amp racks often DON'T ("Parameter not found") → fall back to per-note velocity or a manual envelope. - Drum ghost notes — quiet snares (vel 24–38) ~0.25–0.5 beats before each main snare. Skip the bridge.
- Solo-specific drums — swap constant closed hats for ride on chord-change beats + open-hat splashes at offbeats. ~50% fewer notes; breathing room.
- Pre-solo crash (pitch 49) at the solo's first beat.
- Tom fills at section boundaries — Hi → Mid → Low over 0.5–1 beat, vel ramp 80→110.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ableton-arrangement is a skill published in the GitHub repository PerIPan/music-workflow-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 57 tokens to every session and 2,237 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
