1 beat (quarter note) = 60 000 / BPM ms. Each note value is a multiple of that beat — 1/16 = ¼ × beat, 1/8 = ½ × beat, etc. For sidechain pumping a common starting point is a fast attack (1/16 to 1/32) and a release that opens up just before the next kick (1/4 to 1/8).
For four-on-the-floor pumping at 128 BPM the kick lands every 468.75 ms — set release a touch shorter than that.
