I can help here because this is what I am doing. First off there are some choices. 1. Do you want everything midi? 2. Do you want realtracks. The methods are different.

If I want to orchestrate along a particular style, I will go into preferences realdrums and turn the all drums play as real tracks off so I only get midi. That way I can use my own drum machines instead of the Roland.

There is a button at the bottom that says Make a midi file on the files menu If you click on that it will save your file for you. ---Back up--- I create a folder for the midiversions in the same folder as the styles are with the name of that style. So Styles 4 Larry 2 for a Larry Carlton style that I can pin Revalver onto in Cakewalk X3

If you want to use part midi part real tracks than use REalband and you can generate individual tracks and make sure you save the real tracks independently First because when you go to save midi it will save the midi files but it will erase your real tracks. So save Realtracks first.

Hope this helps.
