It's not as though doing it as separate tracks is always undesirable.
But it would be good to have the option for single tracks that didn't involve the mental overhead of feedback routing and so on.
As I just posted in another thread on the same subject, what I don't get is why it's possible to have a single track both send midi to a VSTi and receive audio from the same vst when you are NOT using multiple outs from the vsti, but the same arrangement isn't possible when you ARE using multi outs.
What's the difference between the two situations? Why is 'feedback' an issue in one case and not the other?

In any case, this seems to be the way it is, for now at least...
