I would have loved to go too....wish they would announce that stuff, more public.
That 809 is really a great instrument...expensive, but discounts are available...a place I used to shop in Ft Wayne,IN discounted that stuff a bunch...my Yamaha HS8-T organ MAP price was around $12K, if I remember well, I paid around $8,500. in 1986 ish
I sometimes do wander if I would be better with a 809, I'm re-thinking if full styles are really the way for me...of course we can turn off channels....but on Yamaha organs they call them Rhythm patterns. I'm going to do more playing on the SX-900 with just basic Rhythm's see how it goes.
Steve and I were talking about touch/feel accuracy at lunch....a piano is more forgiving to hitting adjacent notes etc than a synth kbd. You can kind of feel your way around...I probably didn't say that right, but that's the way I describe it.
A Genos with full 88 note GHA keys would be pretty nice. Clavinova folks at Yamaha would,'t hear of it though.
