Lane: pop/boombaboom/ · peak-time techno · 140 BPM · D minor · 2:27
Source: ~/Downloads/boombaboom.MP4 → sources/boombaboom-raw.wav (a ~32.5s continuous melodic chant, 96% voiced, sitting around C#4 in a D-minor space, with a recurring hook motif E-E-F = "boom-ba-boom").
Treatment (hybrid, @jeffrey's call): the hook is kept as-sung (gently WORLD-locked to the E4/E4/F4 he already sang), the verses are re-mapped — his phonemes WORLD-locked onto a designed rolling D-minor topline.
Bed: c/boombaboom.c, forked from pop/minitek/c/deeptek.c. Keeps deeptek's deep, round, chill kick (96→44 Hz pitch-swept roll, soft click) — no clicky warehouse thud — but adds peak-time drivers: a relentless offbeat open-hat "tss", a warm backbeat clap, a harder sidechain pump (0.80), bigger drop impacts, real breakdowns, and the FM counter-lead pulled back so the vocal hook leads.

Form #

intro(8) build(8) grvA(16) brkdn(8) grvB(16) bigbrk(8) grvC(16) outro(4) = 84 bars / 147s. Drops at 27.4s (grvA), 68.6s (grvB), 109.7s (grvC, lands hardest). The hook repeats every 2 bars through each drop; the re-mapped verse floats over the drum-less brkdn; a held, drenched D4 pad builds tension through bigbrk into the final drop.

Pipeline #

bin/slice-cells.py    # onset-slice source → 29 cells + cells.json (pitch-tagged)
boombaboom.np         # the melodic intent (hook + re-mapped verse + pad)
bin/bake.mjs          # WORLD-lock + rubberband-stretch each cell → place → mix → master

Rebuild everything:

node boombaboom/bin/bake.mjs                          # → ~/Documents/Shelf/boombaboom/

Outputs land in ~/Documents/Shelf/boombaboom/ (boombaboom.mp3 320k + boombaboom-MASTER.wav). Master chain: minitek club master — sub weight under the kick, de-mud, presence, glue comp + soft-clip, loudnorm I=-9 / TP=-1.0.

Conventions used #

WORLD f0-replacement for autotune (bin/pitchsnap_world.py), rubberband only for time-stretch — see [[pop_world_autotune]].
Bottom-up: the music is AC-native C synthesis; only the vocal is a performance layer — [[feedback_pop_bottom_up]].
