In the main Max patch I use, I do a lot of live sampling. I can choose three options for the input for this sampling: a soundfile, a live input or a Rewire device. The main Rewire device I use is Reason and it works fine if I just use it to play pre-programmed songs into Max. However, what I REALLY want to do is play the synths in Reason using my MIDI keyboard and sample the results live in Max. Unforunately, when Reason is Rewire slaved to Max, it won't respond to the MIDI signal from the keyboard. I guess the signal needs to fo THROUGH Max but I haven't been able to figure out how to do that. It may be complicated by the fact that I have another MIDI controller plugged in to control the Max patch with.
I've attached my current Rewire subpatcher from the patch.
