I think everyone missed this thread of mine:
I think Bidule is simply fantastic. It's even great if you want a simple audio recorder to run together with Reason.
I use it for running my Native Instruments plugs and Reason into Ableton Live so I am able to record everything as audio. Fantastic and cool. Reaktor4 with Reason2.5 into Live3: no problem at all!!!
