Sorry - no idea of the price, although I doubt you would even find a used XM2 for $800. In all honesty, I don't realy think its for T4 owners..I just wanted an excuse to use that topic title laugh The KeyB gear is much more specialist and aimed at people who know exactly the sound they are after. I doubt very much that it will end up on arrangers. But I thought it was interesting enough to make a post here.
