Hey Jerry, welcome to the world of Biab and digital audio. To a noob, it's very tricky and confusing stuff.

First, the Real Tracks. They are prerecorded audio files of phrases. They cannot be broken down into single notes, only phrases. The phrases tend to be from one to four bars long. Imagine if you had the horn track only from one of Tower of Power's songs. One phrase might go something like Baa(2-3}ba //ba ba BA baba// That's a prerecorded two bar phrase and that's also what a RT is. Obviously you can't take that prerecorded TOP phrase, put it into Biab and expect that phrase to somehow play what you wrote. It's simply a prerecorded track.

The absolute magic of Biab is all the RT's are full of these phrases and somehow Biab can take the chords your wrote along with the style information and parse all those different phrases together to create a complete track for you, BUT it's still phrases, not single notes. AND not only that, if you regenerate Biab will give you a completely different track from the first one by changing the way it puts the new track together using the same RT phrases. We will have Biab regenerate many times in order to have it come up with a part we like for a particular tune. That's great and all but the big weakness is Biab does it IT'S way not YOUR way. If you want to write exact parts then you have to use midi and synths. And that takes us to...

The second point which is your comment about getting high quality horn sounds to work with. All I can say is welcome to the club. This is what all of the more expensive synth packages are all about. The best ones cost upwards of several thousands of dollars. Basic cheap synths like the Coyote Forte for $40 are fine for basic arranging just to get your song together but to finalize a project to make it sound pro quality you need something like Kontakt or Omnisphere plus a whole lot of knowledge and experience in using them. It ain't easy, that's why people who can do that are called recording engineers.

Native Instruments makes Kontakt and they have a sound library called Session Horns. It's awesome but the regular Kontakt synth by itself is about $5-700 then Session Horns is sold separately for another $300. They do have sales and combo packages from time to time but as you can tell, this is not something you can do for a hundred bucks. You have to treat this like any other worthwhile hobby. People spend thousands on golf or remote control model airplanes for example.

The other possibility is to buy one of the top pro level keyboards that have like 2000 sounds in them. If you play keys as well as horns, that could work too, you just hook up to your computer using a midi or USB cable and Biab will play the sounds from the keyboard. That's called using a hardware synth as opposed to a software synth. Both have their plusses and minuses.

There's way more to this I could write about but this should give you enough to think about for now.
