124 BPM to Milliseconds

Note lengths and delay times at 124 BPM — the tempo of house and deep house. Use the table below to set delay repeats, reverb pre-delay, LFO rates and sequencer steps that lock to the groove.

Set your delay and reverb to 124 BPM

The most common reason to need these numbers is a tempo-locked delay. A delay set to an exact note value stays glued to the rhythm; a delay set to an arbitrary number slowly drifts out of time. At 124 BPM:

Frequently asked questions

How do you convert 124 BPM to milliseconds?
One beat lasts 60,000 ÷ 124 ≈ 483.87 ms. Every other note value scales from that single number: a half note is twice the beat, an eighth note is half, a sixteenth is a quarter, and so on.
What is one beat (a quarter note) in milliseconds at 124 BPM?
At 124 BPM a quarter note — one beat — is 483.87 ms. That is the anchor for every delay, reverb pre-delay and sequencer step at this tempo.
What delay time matches 124 BPM?
The classic choice is a dotted eighth note, which lands between beats and fills the gaps without cluttering the groove. At 124 BPM an eighth note is 241.94 ms, so a dotted eighth is 362.90 ms. A straight eighth (241.94 ms) doubles the repeat density; a quarter note (483.87 ms) sits on every beat.
How long is one bar at 124 BPM in 4/4?
A bar of 4/4 holds four beats, so at 124 BPM it lasts about 1935.48 ms. For other time signatures multiply the quarter-note length by the number of beats per bar.
