Fran’s analysis is right on the money. Often, less is more. At present, I’m playing a Yamaha. I’d love to use some of the big band styles. However, they just don’t fit a quiet dinner party. The brass riffs, intros and endings will blow people away, in a negative way. So, paring down the style parts is necessary, at least for me. That’s why on guitar gigs, I use Band In A Box, for its small combo simplicity.
