Any simplified way to trigger samples according to a set time signature?

Hello,

I'm working on my idea for an 'automatic breakcore' patch. The idea is that you load in drum samples and the patch then plays them according to certain rules for example- two lines in 12/4 and then three in 7/4. Chaos ensues. I've gotten the samples to play randomly and quite nicely so far, but only in a sort of one after the other 4/4 sort of way.

I've got to find a way to be able to switch between time signatures rather quickly, and maybe in the future find a way to automate or randomize which time signature has demand and when.

Can anybody think of a good object or tactic for telling samples when to play according to an odd time signature? Clocker maybe?

I'm a bit lost.

Thanks :)
