174 BPM to Milliseconds
Note lengths and delay times at 174 BPM — the tempo of drum and bass — the genre standard. Use the table below to set delay repeats, reverb pre-delay, LFO rates and sequencer steps that lock to the groove.
Note lengths at 174 BPM
One beat (a quarter note) = 344.83 ms. Values are exact for a straight 174 BPM grid.
| Note value | Straight | Dotted | Triplet |
|---|---|---|---|
| Whole note (1/1) | 1379.31 | 2068.97 | 919.54 |
| Half note (1/2) | 689.66 | 1034.48 | 459.77 |
| Quarter note (1/4) | 344.83 | 517.24 | 229.89 |
| Eighth note (1/8) | 172.41 | 258.62 | 114.94 |
| Sixteenth note (1/16) | 86.21 | 129.31 | 57.47 |
| 32nd note (1/32) | 43.10 | 64.66 | 28.74 |
| One bar (4/4) | 1379.31 | 2068.97 | 919.54 |
Set your delay and reverb to 174 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 174 BPM:
- Dotted eighth (258.62 ms) — the classic choice; falls between beats and fills gaps without clutter.
- Eighth (172.41 ms) — tighter, doubles the repeat density.
- Quarter (344.83 ms) — clear repeats sitting on every beat.
- Bar (1379.31 ms, 4/4) — a slow, spacious echo.
How 174 BPM compares to nearby tempos
Frequently asked questions
- How do you convert 174 BPM to milliseconds?
- One beat lasts 60,000 ÷ 174 ≈ 344.83 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 174 BPM?
- At 174 BPM a quarter note — one beat — is 344.83 ms. That is the anchor for every delay, reverb pre-delay and sequencer step at this tempo.
- What delay time matches 174 BPM?
- The classic choice is a dotted eighth note, which lands between beats and fills the gaps without cluttering the groove. At 174 BPM an eighth note is 172.41 ms, so a dotted eighth is 258.62 ms. A straight eighth (172.41 ms) doubles the repeat density; a quarter note (344.83 ms) sits on every beat.
- How long is one bar at 174 BPM in 4/4?
- A bar of 4/4 holds four beats, so at 174 BPM it lasts about 1379.31 ms. For other time signatures multiply the quarter-note length by the number of beats per bar.
