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.

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.

My goal this weekend is to move just enough each day so that no one pokes me to see if I'm dead or not.
