This question comes up a lot. The key thing to remember is the RT/RD's are audio, everything else in Biab including the melody is midi. My mantra is "midi is not audio, audio is not midi". To try to do what you want is exactly the same thing as taking a CD of you're favorite band and asking how can I change the bass track? The answer is huh? Of course you can't change the bass track of a prerecorded CD without recreating the whole studio session and recording a new bass track. That's what a Real Track is. The brilliance of PG Music is they found a way to take a prerecorded audio track and chop it up using Biab and RB based on a users chord changes and key changes. That audio track can be chopped up down to a one or two bar phrase but it can't be chopped all the way down to a single note which is what you would have to do to use it for a melody track. This is why you still need a good high quality synth to play the midi parts. How much can that cost? The sky's the limit from a few hundred all the way to a high end keyboard that costs three grand or more. A very good compromise of sound vs money is the Ketron SD2 that is sold right here. The sound quality can come pretty close to the RT's and would work pretty well for your melody track. Still, a sax is one of the most difficult instruments to recreate using midi and a synth, it won't sound as good as the RT does because that's a recording of a real sax player in the studio.
