RE: [EXS] Beats per minute

Thanks Ned,

It is hard to believe we used to have to this kind of math all the time
and now, it is gone with the brain cells.  The weird thing is, when I
add 100 cents to a loop in Logic running at 120 it gives me the tempo as
127.1346. It only works out the same as your formula when I add 1200
cents to make it an octave?  I have been Doing the formula as (BPM) x
8.333 % x (the number of semitones) + (BPM) 

So 120 x 8.333 x 1 + 120 = 129.99996  for one semi tone.  Yours is much
easier.  I wanted to build an excel chart for this. So I wanted to make
the formula as simple as possible.  I seem to remember making a chart
like this when I bought my Ensoniq Mirage.

Merci Beaucoup

T'ami

Gary
