EXS 24 Logic Sampler Users Group

Guys thank you for your responses.  I am not sure I explained myself

Here is a reel world example.  I have a loop in my exs that is running
at 120 BPM when I play middle C(C3).  What I want to figure out is the
tempo when I play different intervals.  Let's say I play the same loop
on Bb2, a 1/2 step down.  How do I figure out it's tempo mathematically.
And then of course easily figure out the other speeds at other
intervals.  

Lets say C3=120 beats per minute
	   C4=240 beats per minute
	Now how do I get the other notes in between.  

	Thanks
