The trouble with all this and traditional arranger play is, you HAVE to use pitch wheels and all those other controllers to get the fluid sound of the sax. Basically, a sax player bends, in a small or larger way, almost EVERY single note.

How are you going to play the arranger chords AND sit there with your hand glued to the bender, mod wheel, and all the SA switches and other input devices? This is why, to be perfectly frank, I don't honestly think I've ever heard a LIVE arranger sax solo that sounded even a fraction as good as the audio demos for the SA type sax sounds on the factory demos. These are all done with sequencers, and most likely a two handed first take, then a bunch of editing.

Be interested in hearing anything done live that equals those factory demos...
