I agree, reason has such a great sequencer and mixer I would rather use it as the master. Imagine that having all that reason has to offer plus being able to use other daws inside of it, why not.
I rewire ableton and reason, but I would like to sequence my entire songs in reason becasue of the regroove mixer a type a feel that I can not get out of the other daws. This would also make useing vsti possible.
This actually seems like something Propellerhead could do with cooperation of the major daws. It would give people who use reason as their center peice more creativity.
Their are alot of people who support suggestions, like the idea of vst's, and many who don't; but this is some thing I think we can all agree on
