Scott:
I enjoy all types of music and certainly the category of what is called "smooth jazz" is one of them. There really isn't anything I dislike about it. As with any type of music there are good and bad samples. I do however believe that "smooth jazz" has not evolved enough and seems to be stuck in the same place for a while. It's template tends toward shorter repetitive melodic phrases that don't offer the opportunity to create alternates so you are more or less confined to the chord progressions as the inspiration for improvisation.
As to Arranger bass line repetitiveness I can agree. Although I have found a few styles on my T3 that were interesting. However since adding a Motif XF6 to my setup I can tell you that the Motif offers a fantastic array of infinitely adjustable bass arps that respond to your mode of playing. It is truly amazing.
