Hi all,
I have a track that is 125 BPM
How many milliseconds do I set my delay on guitar pedal for dotted 8th to match 125 BPM?
There must be a way to calculate the milliseconds?

Hopefully the question makes sense, thanks!

125 bpm => 125 beats in one minute.
With one minute being 60 seconds, you have 60 / 125 = 0.48 secs per beat being a quarter note each.

A dotted eighth is one-and-a-half eighth, thus 3/16th.
With one beat being 0.48 secs being a quarter note, 1/16th is 0.48 divided by 4 = 0.12 seconds.
That times three is 0.36 seconds.

You said: 125 bpm

Even note values:
60 ms (32nd notes)
120 ms (16th notes)
240 ms (8th notes)
480 ms (Quarter notes)
960 ms (Half notes)
1920 ms (Whole notes)

Dotted note values:
90 ms (32nd notes)
180 ms (16th notes)
360 ms (8th notes)
720 ms (Quarter notes)
1440 ms (Half notes)
2880 ms (Whole notes)

So the answer is: 360ms!

Oh I see: Bertkoor was faster.

if you don't care how the calculation exactly works, then use this:

I know there is a bug in the long sample calculator somewhere, but I'm too lazy to find & fix it
