congrats on the PA3X! that thing sounds like a beast.
would love to catch up, hear what you're doing musically, etc.
thanks re the book -- it was a great experience.
I dunno re the 910 -- I'm pretty used to the PA800 and tho I miss the simplicity of the yamaha styles, I don't think it's a wise swap. who knows? maybe Korg will have a PA replacement at NAMM....
