Tempo-matched reverb:

  1. Enter your BPM.
  2. Pick a room size and use the pre-delay and decay values shown.
  3. Decay = total length minus pre-delay.

Example (120 BPM): 1 bar = 2000 ms, 1/64 pre-delay ≈ 31.25 ms → decay ≈ 1968.75 ms.

Try slightly offset values for rushing or lagging rhythmic feels.
