How it works
Tempo in beats per minute converts to time per beat with 60,000 ÷ BPM milliseconds. Producers use these values to set delay, reverb pre-delay and compressor release times so effects pulse in time with the music. Dotted notes last 1.5 times as long as the plain note, triplets two-thirds as long.
