Possibly... this feature is in the E/G series OS.

The thing is, as almost identical as the two are, what is the difference between 'pro' and 'home'? Surely not just the speakers? Two analog modify buttons don't exactly scream 'PRO' to me, anyway..!

I'd be pretty tempted by a Prelude with the GW8's soundset and modify buttons. Be even better if it could run off batteries, too! (Had a gig on a yacht recently with no electricity. Had to borrow a POS Casio to do it!)

If there IS a market difference between the two, it is entirely manufactured. I can't really see a lick of difference between 'em...
