I own VA76 and PSR9000. I play it simultaniously -- styles from VA-76 and solo voices from PSR9000.
I am very frustrated by Roland sound and Yamaha styles. But life is better when you play Roland styles and Yamaha sounds.
I think to change PSR9000 for Motif ES and external sound system with subwoofer -- it will give to me best solo sound and multi-pad, but I will keep VA-76 with bad sound but style morphing and vivid styles that sounds like live performance.
I was played Genesys, Tyros and KN7000 (exept SD-1
-- but it all have no such style flexibility like VA-76 with it style morphing.
