Full NTO drum character applied:
- d1 kick: att 0.05 (round thud), lpf darkening over time (saw 800→300)
- d2 clap: quiet (gain 0.7), dry (room 0.1), hpf 800 — mid-snap only
- d3 OH: evolving brightness (n6→n8), att 0.04 (soft onset),
  ^44 toggles whisper-shimmer mode (gain 0.3, hpf 6000, legato 0.15)
- Header: full drum voice analysis with centroid evolution,
  attack/decay times, peak levels per section

Deep demucs drum study findings:
- Kick: 8th note pulse (NOT 4otf), ghost doubles before drop
- Cymbal: THE defining texture, upbeat 8ths throughout most of track
- Clap: appears late (~200s) on contretemps (beats 1&3), ~1200Hz dry snap
- Drop at 2:20: kick disappears, pure cymbal upbeat 8ths
- Arrangement: kick 8ths → cymbal break → kick+cymbal+clap climax

Changes:
- d1 kick: rewritten as 8th note pulse, ^29 ghost double control
- d2 clap: ^43 ON = contretemps (beats 1&3), OFF = backbeat
- d3 hats: OH on every upbeat 8th, ^44 toggles cymbal breakdown mode

Major findings from demucs onset analysis:
- NTO bass uses ONLY F2/A2/C2 (V chord tones) — never sits on Bb root!
- Bass is rhythmically alive, not held notes. Varies each 2-bar phrase.
- Guitar(arp) stem evolves: F3/F4 base → Bb3/A3 mid → Gb4/E4 breakdown
- Piano: sparse Bb3 stabs with F3/A3, only in specific sections

Changes:
- d4 bass: rewritten as rhythmic V chord figure (f2/a2/c2 variation)
- d6 piano: NEW — sparse FMRhodes1 stabs, ^31 knob controls density
- d7 cello: reworked as counter-melody (sustained 5ths/3rds)
- d9 pad: fixed cut group collision (was cut 7, now cut 9)

NTO La Clé des Champs algoraoke:
- Bass: dropped to Bb1/F2 (demucs confirmed 58-87Hz range)
- Bass answer: V chord tones A2→C2→F2 (onset analysis, not Eb Db C)
- Answer timing: quarter notes over 2 bars (was 83ms triplets, now 500ms)
- Arp: simplified to <[bf4 f4]*8!6 [ef4 gf4]*8!2> (no note-flip)
- Cello d7: reworked as sustained counter-melody (5ths/3rds), not bass double
- Drums: added sometimesBy knob control (^30 clap flam, ^32 hat roll, ^52 legato)
- d8 breaks: full treatment (^92 ply, ^60 chop mode, ^36/^56 break switch)
- Header: rewritten with demucs spectral evidence and onset analysis data
- SC: s.volume=2 + StageLimiter.activate for output levels

Research + MIDI analysis of the original track:
- Key: Bb minor (harmonic minor dominant F)
- Arp from MIDI: 2-note 16th oscillation (Bf4/F4, order flips per chord)
- 16-bar cycle: Bbm(4) | F(4) | Bbm(4) | Ebm(4)
- Drums: 808bd+clubkick, h2o handclap, h2o hats (sparse offbeat)
- All melodic voices on MiOmi (bass, arp, pad, lead)
- Timbral faders for live "wider before drop" sweep (FM/detune/cutoff)
