This post sparked my interest. I agree with your feature suggestion. I came up with a workaround though that may or may not be useful. If you chop all your midi segments before rendering then select them all and render they will all render to the same audio track. Doesn’t work for multiple midi tracks though.
Also, you could route the midi track audio output to a specific audio track and bounce live.
Orrr, setup Halion and do all your resampling into there.
I don’t know what you are doing exactly but I resample a lot and these are the things I do.
