what's that formula for determining how much pitchshift i need to get a loop to another tempo?

Your timestretching program should have this already built in. If not, get another one, as it's a pretty common feature. -l On Tue, 13 Mar 2001, laerm wrote:

Presuming this hasn't already been provided (the perils of the digest subscriber :-) here's the formula.

quoted 11 lines The function required to calculate this is:

The above is taken from a site which gives a javascript calculator that does exactly this. If you think it'll save you time, you could save the following web page off to your hard drive. http://www.birdsoft.demon.co.uk/music/sampcalc.htm Hope this helps!
