Don,

At my age I need the transfusion. I love the X1 but to be honest I've never been all that impressed with the swing and big band styles (remember that I've played in a 16 piece big band for 26 years). I think that they are a little too busy sounding. I love the ballads, country, and latin styles of the X1 but for BB and Swing I'm using converted Technics and Korg styles more than anything else. So I guess yes, I'm not completely satisified and maybe some Yamaha styles would help. I feel that the X1 could also use a few more classic rock styles.
