Some of the threads here have touched on getting good Sax sounds out of JABB3. It has been a long-standing effort of mine to get something decent sounding. To start with some credible reference material, I got the Sammy Nestico book "The Complete Arranger (Rev ed.)". It has scores and a CD to tell you what it sounds like. I used the first example which is about 9 bars of "Invitation" and created a MIDI mockup.
Parts of the book can be found here at Scribd (The Complete Arranger) on page 18.
An MP3 of the MIDI mockup along with the Sonar Project, a screen capture, and the Alto Sax track as a MIDI file are here. Hopefully, this is helpful to other that are trying to climb the curve of effective JABB3 rendering and MIDI mockups.
