Get note-based pre-delay and decay times in milliseconds for any tempo, so your reverb sits in the pocket instead of washing out the mix.

A pre-delay of a 1/64–1/16 note keeps transients clear before the tail arrives. For decay, set the reverb tail to die out by the next beat (tighter) or bar (lusher) so it breathes with the tempo.
How it works
Pre-delay is the gap before the reverb tail begins; setting it to a 1/64–1/16 note keeps transients clear. Decay is how long the tail rings — tie it to a beat for a tight ambience or a bar for a lusher space. All values are derived from the quarter-note length, 60000 ÷ BPM.
FAQ
Why sync reverb to tempo?
Tempo-synced pre-delay and decay let the reverb tail resolve with the music instead of smearing across the next chord, keeping dense mixes clear.
Is more pre-delay always better?
No — a longer pre-delay separates the source from the tail (good for vocals), but too much sounds like a distinct echo. Use the note values as starting points.
