I don't sing, I don't GIG out, I play the more smooth type music, ballads, musical theatre, 50. 60 love songs...easy listening mostly...so for me the Yamaha has the best sounds AND styles for my type of playing. I had a Korg PA2XPRO, and sent 3 pages of data to them highlighting the samples and sound programming that needed serious work, never heard a thing back.
I'm a old organ player at heart, had Conn, Thomas and several Yamaha's....and I want/need great Orchestral sounds mostly...Genos is king for me, but I may go SX900 for now.
