What this is for

Most delay, reverb, and tremolo plugins ask for a time in milliseconds. This converts any BPM into the exact ms value for any note length.

Use it when your plugin doesn't have a "sync to host" toggle.

Reading the table

  • Normal — straight rhythm.
  • Dotted — 1.5× the normal value. Syncopated, leaning feel.
  • Triplet — 2/3 the normal value. Polyrhythmic and lively.

The math

ms per beat = 60,000 ÷ BPM

At 128 BPM: 60,000 ÷ 128 = 468.75 ms per quarter note.

Frequently asked questions

How do I convert BPM to milliseconds?
Divide 60,000 by the BPM. For 120 BPM, one quarter note equals 500 ms. Dotted values are 1.5 times the straight value; triplets are two thirds of the straight value.
Why do producers convert BPM to milliseconds?
Delay and modulation effects take millisecond inputs. Converting BPM to ms lets you sync effects to the tempo of a track, so the repeats land on the beat and support the groove instead of clashing with it.
What is a dotted delay time?
A dotted note is 1.5 times the length of the straight note. A dotted eighth note delay at 120 BPM is 375 ms. This creates a syncopated rhythmic shimmer that sits between the beats.
