Adding to Videotrack's message the Ultrapak also comes on a HD.
You will find that the MIDI drum tracks in BiaB are very good. Sometimes I will use them as is while other times I may either rewrite a small section and/or use Groovemonkee MIDI loops.
https://groovemonkee.com/As previously stated there is nothing wrong with the way you want to use BiaB. I drag and drop MIDI and RT tracks into my DAW, Studio One Pro, with no problems. In fact I use the exact same method as you are proposing to use.
Good luck.
