How to calculate delay time from BPM: the 60,000 trick

Sound on: the before and after is in the video.

Divide 60,000 by your BPM to get one beat (a quarter note) in milliseconds. At 120 BPM that's 500 ms. Halve it for an eighth note (250 ms), halve again for a sixteenth (125 ms), and multiply an eighth by 1.5 for a dotted eighth (375 ms). Echoes timed like this land on the groove instead of fighting it.

How to do it

  1. Find your BPM.
  2. Work out 60,000 ÷ BPM. That's a quarter note in ms.
  3. Divide by 2 for an eighth note, by 4 for a sixteenth.
  4. Multiply by 1.5 for dotted notes, or by 2/3 for triplets.
  5. Or switch the delay to tempo sync, or use a calculator that does it for you.

Why it works

Echoes that land between the beats blur the rhythm. Echoes on the grid add to the groove, and the dotted eighth is the classic that bounces against straight beats.
