Work out tempo to milliseconds instantly with clear inputs, formula shown and shareable results.
A quarter note lasts 60000 divided by the tempo in milliseconds, and other divisions scale that value, with a dotted note at 1.5 times and a triplet at two thirds. Setting a delay to a note division rather than a round number is what makes echoes sit in the groove instead of blurring against it.
Quarter note
milliseconds = 60000 / tempo
Other divisions
multiply the quarter note period by 4, 2, 0.5, 0.25, 1.5 for dotted, or 2/3 for triplets
milliseconds = 60000 / tempo. A quarter note lasts 60000 divided by the tempo in milliseconds, and other divisions scale that value, with a dotted note at 1.5 times and a triplet at two thirds.
