Tempo Calculator
Loop lengths and delay timings
Set the BPM — the calculator immediately shows you every important time value. Perfect when you want to use delays and echoes musically or understand loop lengths.
What you learn with it
How tempo and time relate. A 4-bar loop at 128 BPM lasts exactly 7.5 seconds — knowing that makes you faster and more precise.
How to use the tool
Set your track's BPM with the slider (or type it in directly)
Loop lengths: how long do 1, 2, 4, 8… bars last in milliseconds?
Delay timing: which note should your echo/delay land on?

All values update live as you move the slider
For a musical echo: set the delay to a 1/4 note or a 1/8 note. At 128 BPM a 1/4 note is 468 ms — enter that straight into your FX unit.

Take the time in one go — hearing and timing develop through repetition, not through reading.
