Wow that sounds doable, but for something like that, Fruity loops is about a couple light years ahead if you have your completed loops....also the MV8000 does this flawlessly....I mean not getting off the point but it sounds doable but working with what you have it seems like not too much of a built in function....now I bet you could take your individual patterns in wave....convert with recycle to rex....then use your recycle loop player, with as many instances of the player needed then sequence your patterns like that....I dunno about the imitiation triton plug though, it might work, oh another thought how about using the redrum or one of the other samplers and assign a pattern to individual keys...seems like that would work...I am only speculating but I have used reason a ton of times but never for what you are talking about.
