feat(copycat): melodic rework — demucs onset analysis, controller mapping 

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

-- HARMONIC ANALYSIS (chordu.com + demucs htdemucs_6s spectral)
-- =============================================================
-- Key: Bb natural minor (Bb C Db Eb F Gb Ab)
-- with harmonic minor dominant (F major, not Fm → raised 7th = A natural)
-- with harmonic minor dominant (F major → raised 7th = A natural)
--
-- Main chords:
-- Bbm (i) = Bb Db F — tonic, home base
-- F (V) = F A C — dominant (harmonic minor), drives V→i cadences
-- Db (III) = Db F Ab — relative major, appears in extended sections
-- Ebm (iv) = Eb Gb Bb — subdominant minor, tension before resolution
-- Gb (VI) = brief appearances
-- Chords (Bb harmonic minor):
-- i Bbm = Bb Db F — tonic, home base
-- V F = F A C — dominant (harmonic minor), V→i cadence engine
-- III Db = Db F Ab — relative major, extended sections
-- iv Ebm = Eb Gb Bb — subdominant, tension before resolution
-- VI Gb — brief appearances
--
-- Primary vamp: Bbm | F alternating (4 bars each, ~8 seconds)
-- Extended sections introduce Db and Ebm for variation/tension
-- The V→i cadence (F → Bbm) is the main harmonic engine
-- Primary vamp: Bbm | F alternating (2 bars each)
-- Extended: Bbm | F | Bbm | F | Bbm | F | Db | Ebm (16-bar cycle)

-- ARRANGEMENT (approx for 6:56 track)
-- ====================================
-- 0:00-1:30 INTRO Filtered pad, atmosphere, gradual reveal
-- 1:30-2:30 BUILD Kick enters (4otf), bass creeps in, hat opens
-- 2:30-3:30 GROOVE Full drums, arpeggio enters, bass locked
-- 3:30-4:30 MAIN All elements, lead melody interplay
-- 4:30-5:30 BREAK Kick drops, pad swells, filter sweep tension
-- 5:30-6:30 CLIMAX Everything returns, peak energy
-- 6:30-6:56 OUTRO Elements strip away, reverb tails
-- BASS stem: 86Hz (F2) dominant across all segments
-- Bb1=58Hz (sub band), F2=87Hz (low band), C2=65Hz (passing tone at 120s)
-- Sub/low ratio shift reveals root movement: high sub% = Bb1, low sub% = F2
-- → Bass sits in Bb1-F2 range, NOT Bb2-F2 (deeper than initially coded)
-- → C2 passing tone at breakdown (seg_0120) = scale degree 2
--
-- ARPEGGIO (from MIDI: Nto- la cle des champs .mid)
-- ==================================================
-- Two-note 16th oscillation — dead simple, magic is in timbre:
-- Bbm: Bf4 ↔ F4 (root + 5th, Bb on downbeats)
-- F: F4 ↔ Bf4 (SAME notes, ORDER FLIPS — F on downbeats)
-- Ebm: Ef4 ↔ Gf4 (root + minor 3rd)
-- Before ~4:30 breakdown: synth widens/brightens (more harmonics,
-- phaser-like) then drops back → fm1/detune/cutoff on faders
-- PIANO stem: enters ~40-50s, peaks ~90-100s
-- 237Hz (Bb3) dominant, 53% low + 47% mid
-- → Rhodes-style chord stabs in Bb3-F4 range (low-mid, not high)
--
-- GUITAR stem (= arp synth, demucs mislabel):
-- 172Hz (F3) dominant, peaks at 100-120s and 250s
-- → Mid-range synth arp, NOT the bass register
--
-- OTHER stem (= pad/atmosphere):
-- 226Hz (~Bb3) dominant early, shifts to 345-560Hz later
-- → Pad evolves: low-mid warmth → brighter harmonics over time
--
-- MIDI TRANSCRIPTION (Nto- la cle des champs .mid)
-- =================================================
-- Arp: Bb4↔F4 16th alternation (Bb on downbeats), same notes over both
-- Bbm and F chords (context changes beneath). Eb4↔Gb4 for Ebm.
-- Note order does NOT flip between chords — Bb stays on top.
-- Kick: Offbeat syncopated pattern (NOT straight 4otf throughout)
--
-- ARRANGEMENT (demucs segment timeline)
-- ======================================
-- 0-10s: Pad only (other stem: Bb3, rms=0.07)
-- 10-30s: Bass enters (86Hz/F2, rms=0.19-0.26), pad continues
-- 30-50s: Arp synth fades in (guitar stem: 172-183Hz), piano first stabs
-- 50-60s: Build (all melodic voices growing)
-- 60-90s: Drums enter big (kick 54Hz/93% sub at 65Hz), full groove
-- 90-120s: Piano peaks (237Hz, rms=0.05), all voices at full
-- 120s: Breakdown — bass drops to C2 (65Hz), arp peaks, drums thin
-- 150s: Piano reprise, mid-frequency evolution
-- 200s+: Climax sections, pad shifts bright (560Hz), full energy
--
-- SOUND DESIGN
-- ============
-- KICK: 808bd sub + clubkick body, 4otf
-- BASS: MiOmi sub (Moog-like FM), melodic through chord tones
-- ARPEGGIO: MiOmi 2-note 16th oscillation, FM/detune/cutoff on faders
-- PAD: MiOmi detuned, generous reverb, slow filter
-- KICK: 54Hz/93% sub (demucs). Deep techno sub-kick, NOT a bright 808
-- BASS: Bb1-F2 sub (58-87Hz). Moog-like, melodic root movement + answer
-- ARPEGGIO: 2-note 16th Bb4↔F4, FM synth. Magic = timbre not notes
-- PIANO: Rhodes stabs, Bb3/F4 area, enters ~40s, peaks at 90s
-- PAD: ~Bb3 warm bed, evolves brighter. Generous reverb, slow filter
-- HATS: h2o velocity-layered, sparse offbeat + flourish
-- CLAP: h2o natural handclap, reverbed
--
-- NTO'S KNOWN GEAR:

-- PRODUCTION STYLE (from interviews):
-- "I love the 'human side' of electronic music. When the
-- different elements sound autonomous and organic."
-- Process is "really random" — may start from a concept
-- (track, film, photo, emotion) or just experiment.
-- Influences: Stephan Bodzin, James Holden, Paul Kalkbrenner
-- "I love the 'human side' of electronic music."
-- "Deep basses and lysergic harmonies"
-- Often asks real musicians to replay his software melodies
-- for organic feel (e.g. Worakls on keys/guitar)
