Hi Randy,
the sx just doesn’t quite have the depth of sound of the real sax , if it did, your keyboard playing skills are so good, I’d be hard pressed to tell which is sax and which is keyboard.
Rikki - thanks so much! Yes, I was a little surprised the SX900 sounded as realistic as it did on the same track. There are nuances that can only be injected via the mouthpiece and breath stream (volume, inflection, and some emotion via lip and vibrato changes) that are not feasible on the keys, but if a person worked at it and selected the licks properly, the keyboard does offer a usable alternative. Thanks for the listen!
