I guess I'm the odd ball among the group. Having owned tons of arranger boards, not one has ever left the house for gigs. Reason: I'm a guitarist, who sings as well. I create my own backing tracks on a Tyros 2 (and sometimes BIAB). I add generous overdubs as needed and vocal harmonies. All this is played from an iPod in "live" settings. This approach works well for me. I average 8 to 10 gigs per month and play everything from the 20's through the 70's. My market doesn't require much from the 80's onward---and that's fine with me. Since I'm not a two-fisted player like many on this forum, my primary interest (in new arrangers) is in the styles and the realism of a band. I appreciate all the reviews, comments, and contributions of you with the real keyboard chops. It's helps those of us who play chords and arrange to make decisions on the latest products to assist in our solo efforts.
