I agree Scott. Bass lines in the existing styles are one of the things that I always disliked about the Yamaha styles in general. I too am more of a jazz oriented player, ( along with a healthy dose of blues of course ), although I am more into Jazz Fusion, Modern, and Acid jazz, but the styles don't suit these genres any better than they do Swing or Big Band styles of Jazz. The simple bass lines in Yamaha styles probably work pretty well for doing top 40 classics and 8 and 16 beat ballads as well as other genres along those lines. In reality, it's tough enough anyway for me to be expressive with any manufacturers styles, for what I like to play best, but Yamaha's are among ther poorest choices for me. ( but pretty cool when I go to a rock ballad or 16 beat ballad ) I think most of the stuff I'm happiest with when doing Jazz genres if I don't do it all manually gets started in Jazz++ sequencer and sometimes Jammer Pro with a reworked or custom made style. Should I wish to use these patterns in a real time setting, Style making / Conversion programs are a true blessing as well.
