Using Multiple Controllers Simultaneously Options

[gleit]

I'm trying to connect several midi controllers to reason 2.5, the idea being to do a live act with electronic drums, a midi bass and a keyboard (driving redrum and two synths). But it appears the sequencer can only record one midi controlled instrument at a time.
I think I can maybe hook the three controllers up, but I'm pretty positive reason won't be able to record them all at once (and I wanna be able to record all jams).
Does anybody out there have any experience doing something similar? Like, for example, having three keyboard controllers driving 3 different instruments at the same time?
Anybody know any software packages that can do this?
