I didn't try the patch, as I don't have Gem installed, and as a result I 
may be missing the point in what follows.  But some useful equations 
(which you can rearrange using very basic algebra):

(time per frame in ms) = 1000 / (rate in fps)

(total time in ms) = (number of frames) * 1000 / (rate in fps)

(time per beat in ms) = 60000 / (rate in bpm)

A way of checking equations for plausibility is described in the first 
few paragraphs here:
