Bill, thanks for sharing your Wersi Abacus produced demo. I'm quite impressed with the drumkit & organ sounds. Your posted demo seems timely, because when I attend NAMM last week, and had stopped by the Wersi Showroom to checkout the Abacus, I was TOTALLY IGNORED by the Wersi showroom staff (5 people), even though not a single other visitor was in the room. After 8 minutes, and not a single Wersi rep even willing to acknowledge my presence, I left the room. Bill, your song medley demonstrates how impressive this instrument sounds, but that bad experience with Wersi at NAMM has left a bitter taste in my mouth, including no interest in purchasing a Wersi product now. - Scott
