Press T (or sky menu): an Ableton-shaped tracks view for casuals. Every voice
is a track, eight bars across; each cell cycles live (the world plays the
lane) -> clip A/B/C (patterns on the existing groove grids, A/B pre-seeded so
it makes music immediately) -> silent. Double-click a clip to edit its groove
in the piano roll (shared-reference write-through). Play loops the arrangement
on the godtime clock, one column per bar; stop hands the voices back to the
world. Arrangements serialize with patches; note lanes play out over MIDI
live, and "export .mid" writes a type-1 Standard MIDI File (96 ppq, tempo
meta, lead ch0 / bass ch1) — encoder logic unit-tested by parse-back.
