Frequently asked questions
What is the calculator useful for in practice?
For example for delay times, reverb pre-delays, sidechain rhythms or LFO syncs if you want to quickly switch between BPM and milliseconds.
How long is a quarter note at 120 BPM?
A quarter note at 120 BPM is exactly 500 milliseconds.
What is the difference between eighth and dotted eighth?
The dotted eighth is half longer than the normal eighth. It corresponds to a factor of 0.75 of a quarter note.
