Seems i was mistaken, although it would be possible if you had reason on a seperate machine and hooked up your audio interface to the input and output of that machine
Otherwise you can still import audio into Reason and do what you want with it.
Yes if you have two soundcards it's also possible without using things like jackaudio.
