First playable pass at Rose Rouge. 118 BPM, the `rose` bank carrying both the
voice and the horns, and the d5 line walking the sample index by hand
("<5 6 7 8 9 10 11 11 12 13 14 13 15 16 17 18 20 21 22 23 ...>") because the
phrase order IS the arrangement — LE TOUR DU JAZZ.

The d7 vocal chops keep their own lookup table in the comments, mapping `end`
to the words it lands on:

  0.2  i wan'
  0.3  i want you
  0.5  i want you to get to?

That table is the score. Committing it now so the next session does not have to
re-derive it by ear.

Committed as an MVP, warts included, because three of its lines are sitting on
the unseeded-control bomb found this afternoon (#156) and I want the BEFORE
state in history:

  * d1  midiOn "^41"                      -> orDef 0, so the 4/4 floor variant
                                             plays on 0% of cycles and the
                                             syncopated one plays forever
  * d4  # crushbus 41 (range 16 4 "^35")  -> BARE ^35 in a `#`: no events at
                                             all, the bass is structurally
                                             silent until that knob is moved
  * d11 # delay (range 0 0.9 "^19")       -> same shape, same silence

None of that is a bug in the track. It is the boot's control map starting empty,
and the fix lands next commit. This file is the test case.
