128 BPM to Milliseconds
Note lengths and delay times at 128 BPM — the tempo of club standard — house, techno and the edm drop. Use the table below to set delay repeats, reverb pre-delay, LFO rates and sequencer steps that lock to the groove.
Note lengths at 128 BPM
One beat (a quarter note) = 468.75 ms. Values are exact for a straight 128 BPM grid.
| Note value | Straight | Dotted | Triplet |
|---|---|---|---|
| Whole note (1/1) | 1875.00 | 2812.50 | 1250.00 |
| Half note (1/2) | 937.50 | 1406.25 | 625.00 |
| Quarter note (1/4) | 468.75 | 703.13 | 312.50 |
| Eighth note (1/8) | 234.38 | 351.56 | 156.25 |
| Sixteenth note (1/16) | 117.19 | 175.78 | 78.13 |
| 32nd note (1/32) | 58.59 | 87.89 | 39.06 |
| One bar (4/4) | 1875.00 | 2812.50 | 1250.00 |
Set your delay and reverb to 128 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 128 BPM:
- Dotted eighth (351.56 ms) — the classic choice; falls between beats and fills gaps without clutter.
- Eighth (234.38 ms) — tighter, doubles the repeat density.
- Quarter (468.75 ms) — clear repeats sitting on every beat.
- Bar (1875.00 ms, 4/4) — a slow, spacious echo.
How 128 BPM compares to nearby tempos
Frequently asked questions
- How do you convert 128 BPM to milliseconds?
- One beat lasts 60,000 ÷ 128 ≈ 468.75 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 128 BPM?
- At 128 BPM a quarter note — one beat — is 468.75 ms. That is the anchor for every delay, reverb pre-delay and sequencer step at this tempo.
- What delay time matches 128 BPM?
- The classic choice is a dotted eighth note, which lands between beats and fills the gaps without cluttering the groove. At 128 BPM an eighth note is 234.38 ms, so a dotted eighth is 351.56 ms. A straight eighth (234.38 ms) doubles the repeat density; a quarter note (468.75 ms) sits on every beat.
- How long is one bar at 128 BPM in 4/4?
- A bar of 4/4 holds four beats, so at 128 BPM it lasts about 1875.00 ms. For other time signatures multiply the quarter-note length by the number of beats per bar.
