Dotted minim: A note worth 3 crotchet beats. The dot extends the value by half as much again, i.e. 2+1=3. Triplet: Each note is worth a third of a beat. The crotchet beat is divided into 3 instead of the usual 2.

A dot written after a note adds one-half of the note’s value to the original note’s value. A quarter note equals one beat. A dot after the quarter note adds ½ beat (½ of the original value). A dotted quarter note equals 1½ beats.

If you are in 6/8 timing the quarter note is usually said to be worth two eighth notes – so the dotted note is worth two plus half of two, so 3.

1. a dotted half-note is 3 beats instead of 2 (2+1)
2. a dotted quarter is 1.5 beats (1 + 1/2)
3. a dotted eighth is 3/4 of a beat (1/2 + 1/4).

Dotted Eighth Notes The dot adds one-half of the duration value of the note to itself. For instance, one half the value of a half note is a quarter note.

Dotted-eighth delay sets the repeat to land on the last sixteenth-note of the beat, and can essentially make a scale played in eighth-notes sound like a melodic sequence of sixteenth-notes.

Let us start with the simple maths calculation.

1. Divide the BPM of your mix by 60.
2. Halve the 1/4 note value (or divide by 2) and you get the 1/8 value.
3. Halve the 1/8 note value (or divide by 2) and you end up with the 1/16 value.
4. To calculate Dotted Value multiply the calculated delay value by 1.5.

How to Calculate Delay Time to Tempo Beat

1. * Delay time in ms (Milli-seconds) = 60000/BPM (Beat Per Minute)
2. Will give you a quarter note delay time.
3. OR.
4. * Crotchet (Quarter note) timing in ms (Milli-seconds) = (BPM) = 500 ms.
