Tempo-synced delay and reverb times: every note value in milliseconds and Hz for your BPM, with dotted and triplet variants.
| Note | Straight (ms) | Dotted (ms) | Triplet (ms) | Hz |
|---|
One beat (quarter note) lasts 60000 ÷ BPM milliseconds — 500 ms at 120 BPM. Dotted values are 1.5x, triplets 2/3x. Use the ms column for delays and reverb pre-delay, the Hz column for LFO rates. Common trick: set pre-delay to a 1/64 or 1/128 value so the reverb breathes with the track.
One beat (a quarter note) is 60000 divided by the BPM: 500 ms at 120 BPM, 400 ms at 150. Halve for eighths, halve again for sixteenths; dotted notes are 1.5 times longer and triplets two thirds.
Delays set to note values (1/4, 1/8, dotted 1/8) repeat in time with the song, so echoes reinforce the groove instead of smearing it. The dotted 1/8 is the classic U2-style guitar delay.
Rate-based effects (LFOs, tremolo, auto-pan) are set in Hz. A quarter note at 120 BPM equals 2 Hz, so the table lets you sync free-running LFOs to the tempo by hand.
