128 BPM in Milliseconds: Delay Times and Note Lengths
At 128 BPM one beat (a quarter note) lasts 468.75 ms and one bar of 4/4 lasts 1.875 seconds. Below are the delay times for every note value, the same notes in Hz, bar and phrase lengths, samples per beat and the genres that typically sit at this tempo.
128 BPM at a glance
- One beat at 128 BPM lasts 468.75 ms (60,000 divided by 128), an eighth note about 234.38 ms and a dotted eighth about 351.56 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 125 BPM, with 480 ms per beat.
- At 48 kHz a beat is exactly 22,500 samples, while at 44.1 kHz it is 20,671.875 samples, so a loop cut on the beat lands on a whole sample only at 48 kHz.
- A 4 bar phrase in 4/4 takes 7.5 seconds, and 3 minutes of music at this tempo holds 96 bars of 4/4.
- Going from 128 to 129 BPM shortens each beat by 3.634 ms, about 0.78% of the beat.
- An LFO synced to quarter notes runs at about 2.133 Hz; synced to whole bars of 4/4 it runs at about 0.5333 Hz.
