Delay & reverb times at 90 BPM
At 90 BPM one beat (a quarter note) is 666.67 ms, so an eighth-note delay is 333.33 ms and a sixteenth is 166.67 ms. Dial any of these into your delay or set a tempo-synced reverb's pre-delay to the sixteenth and its tail to fade around a beat or two. The full chart above covers every note value.
The dotted-eighth delay at 90 BPM
The famous dotted-eighth delay — the shimmering, off-grid repeat behind countless guitar and pop productions — is 500 ms at 90 BPM (1.5× the 333.33 ms eighth note). A triplet delay is ⅔ of the plain note instead, giving a rolling, galloping echo; both columns are in the chart.
90 BPM in context
Ninety BPM is the engine room of 90s hip-hop and reggae. It is the tempo of countless classic boom-bap records and the steady one-drop of roots reggae — a relaxed walk that still carries real momentum. Practise against it in the 90 BPM metronome — the only one with named human feels.
