Whats the maths to work out how much delay to use someone told me to divide 60000 by the bpm can anyone help me???

i'm sorry but the question doesn't make sense to me you'll need to be more specific i'm afraid... 60k/bpm would yeild #ms per beat if thats what your asking...

am researching techniques of mixing for my uuni work and id seen osomewhere about getting your delay better intime with the flow of my music is that the techniqe that will help?

yeah i suspect that's what your after.... converting beats to msec... and then if for instance you want a triplet delay you could then devide it by 3.... make sense???

~~~~~~~~~~~~~ begin math lesson ~~~~~~~~~~~~

1 minute is 60000ms.

Beats-per-minute = beats-per-60000ms.

If you take, say, 95 bpm, and you'd like to know how many ms are in each beat,

95 beats/60000ms = 0.001583 beats-per-millisecond.

Now you need to find the reciprocal of 0.001583, or 1/0.001583

which is 631.58 milliseconds-per-beat.

So, if you'd like your delay to repeat 2 times per beat, you'd need to cut that in half, or 315.79 milliseconds. If you want 4 repeats per beat, you'd divide by 4...etc.

Now, the master formula:

1/(b/6000) = milliseconds-per-beat, where b is your tempo
in beats-per-minute

Then divide that number by how many times you'd like it to repeat per beat. I've found that you can round off the amount after the decimal and not notice.

Yes, it was perhaps a little over-complicated.

There are 60000 milliseconds in a minute, so just divide 60000 by the beats per minute to get the time per beat in milliseconds.

Then divide that figure by the number of intervals per beat to get the interval time in milliseconds.

For the example of 95 bpm and 4 intervals (repeats) per beat:

60000 / 95 = 631.58 milliseconds per beat

631.58 / 4 = 157.9 milliseconds per interval
