I owned two Roland Keyboards and for one reason or another got stuck with Yamaha ones. Still regret to this day I sold the Rolands and did not buy a BK9 when I had the chance. Too late now. I'm getting better and better along with the PSR S975, don't gig anymore, so I should be satisfied with what I have, even though I miss additional keys, although an 88 with a module is something to consider.(?)
