Delay time = 60,000 ÷ BPM for a quarter note. Use these values to sync delay and reverb pre-delay to the tempo.

120 BPM = 500 ms per beat

At 120 beats per minute, a quarter note lasts 500 ms and an eighth note 250 ms.

Step by step

  1. Quarter note = 60,000 ÷ 120 = 500 ms.
  2. Eighth = half of that: 250 ms; dotted eighth = × 0.75 of a quarter: 375 ms.
  3. Triplet eighth = quarter × ⅓: 166.667 ms.

120 BPM is a dance tempo — house and pop sit around 118–130 BPM. A 3-minute song at 120 BPM has about 360 beats (90 bars of 4/4).

How it works

Tempo in beats per minute converts to time per beat with 60,000 ÷ BPM milliseconds. Producers use these values to set delay, reverb pre-delay and compressor release times so effects pulse in time with the music. Dotted notes last 1.5 times as long as the plain note, triplets two-thirds as long.
