So, I;m entering notes for my piano students' examples. I use Finale for this. With dynamics, articulations, and tempo modifications entered, the Finale playback sounds quite lifelike. Crescendos, tremeloes, slurs, etc., are all played back quite accurately.

Since note step-entry in BIAB is horrible, and offers no attention to dynamics, I'd like to import the piano part as a .mid file, bringing in articulations, dynamics, and tempo alterations to help shape humanize the playback. I'd also like this extraneous performance information to affect how the backing ensemble accompanies the melody.

Is that too much to assume? What about if I imported the Finale track as an audio file? Will the dynamics, tempo alterations, articulations,etc., come across to the backing instrumentation?
