Apple Logic Pro /LogicExpress Discussion

I was wondering if anyone could give me some pointers for working with 
ultrabeat.

either an easy way to record an ultrabeat pattern to a track as audio, 
or better yet, a way to place midi patterns in the sequence window for 
x number of bars, and just have them play ultrabeat (I'm used to 
working with reason for this sort of thing, in case anyone is familiar 
with that and could use it as a touchstone).  right now it just plays 
forever, and I have not found an easy way to work with it.   I 
discovered how to turn patterns on and off with midi notes, but as a 
toggle it often does not work as I would like it to.

thanks -
