Apologies if I have missed something obvious, but is it possible to use Reason as a multitimbral sound source with Max.

I have been attempting this with the recent ReWire tutorials, but Reason only seems to want to play one instrument at a time.

I am sure that it is something pretty simple, but I am stumped.

you can target different sound generators by targeting separate midi channels, and selecting them w/r/t your setup in reason.
