George,
I have a few friends that are out there with you at the show. See if you run into Dom Troilo (from Medley Music in Bryn Mawr Pa), or Don & Linda Moyer (from Pro-Line Music in Fairless Hills Pa).
I wish I was with you! I love fooling with the new stuff. You may find Don & Linda at the Korg booth - he's interrested in the Pa80....same as me. Have fun!
