The sound you get from BIAB or Real Band when you play *.mid files or midi like files is going to be dependent on your sound card. If the sound card is crap the sound will be crap. The exceptions to this of course is if you use Real Drums and Real Tracks within these programs.
Now the scolding!
Read, read and re-read the manuals that are included in the BB & RB folders as PDF files. I can tell you haven't. Both programs are extremely complex. Read this stuff and then we can better help you as you progress but you've got to get the basics under your belt first.
