Hi, just 2 little questions if someone can help me!

In a standard Jazz if I want to create a solo only on the first 4 bar of intro, then create a melody and after the first chorus start with a solo is possible?
I can't generate the solo on the intro before the melody. After the first chorus I found the solution but not only for the firs 4 bars.

Second: the real track (the sound) of the tenor sax I used for solo is very good, but the sound that BIAB uses for melody (generate with melodist) is not so good (in both cases they are TENOR SAXES).
Is possibile to set the same sound or I have to manage 2 different kind of sounds?
Thank you
Toni
