@jeffrey: "can 'in' start a half beat sooner · also lets have the prelude kick sound too · a kick before the first beat i mean". Moving "in" earlier means shortening "up", and shortening "up" moves its peak — the offset scales with the stretch, so the peak that had been placed on beat 7 slid to 6.92 as soon as up lost half a beat. Solved it rather than iterated: the peak sits about 0.315 of the slot in, so with the slot ending at 8.29 the duration that keeps the peak on 7 is 1.88, which puts curled at 2.41. Verified — in starts 8.29, up peaks at 6.96. The pickup kick comes back, at 0.019 s against a beat 0 of 0.510 — so there is a kick under her /s/ before the downbeat.
