Tempo in milliseconds
How long each note value lasts at your tempo, to set a delay, a reverb or an LFO.
At 120 BPM, a quarter note lasts 60,000 divided by 120, which is 500 milliseconds. An eighth note lasts half as long, a half note twice as long.
| Value | Straight | Dotted | Triplet |

| Whole note1/1 | |||
| Half note1/2 | |||
| Quarter note1/4 | |||
| Eighth note1/8 | |||
| Sixteenth note1/16 | |||
| 32nd note1/32 |

The math is always the same: a quarter note lasts 60,000 divided by the tempo, in milliseconds. A dotted note lasts one and a half times its value, and a triplet note two thirds of it, since you play three in the time of two. For an LFO, the frequency in hertz is 1,000 divided by the length in milliseconds.
Where do these numbers go? Into the time of a delay that does not sync on its own (the dotted eighth is a classic), into the pre-delay of a reverb (a sixteenth or a 32nd note, so the reverb starts in time), into the release of a sidechain compressor (so the volume comes back up just before the next kick), and into the rate of an LFO, in hertz.
