Thanks for the quick answers. All I have is a fast Windows 7 Pro PC with 12gig of Ram and a terabyte of disc space and a Real Tech HD Audio card. By synth, is that a keyboard device (like a portable electric piano, that has a MIDI output)?

I don't have synth yet, but I would like to have something that can produce realistic Trumpet, Trombone, and Sax sound as well as some good strings. The built-in Real Drums, Real Bass, and Real Guitars do an amazing job for the rhythm sections, but I would really like some believable horns. Can you recommend a synth or other device to help my arrangements that isn't too expensive?

As you can see, I'm a real newbee at this. I even have a lot of questions about the BIAB system - like why does the wav output not get all the channels or recognize mutes,etc/

Thanks so much for your help. I'll probably nag everyone crazy asking questions.
