Yamaha Clavinova CVP 509:


A traditional piano player would ideally want 88 notes, plus fully weighted 'hammer action' keys to boot. The 88 note Yamaha CVP 509, of which incorporates Tyros 3 level SA voices and auto accomp features satisfies the full 88 note requirement, and the CVP 609, due out later this year will incorporate Tyros 4 level SA voices and styles, so the choice is already available soon for folks who want a full 88 note range Tyros keyboard. Owning and playing a Steinway B Grand as well, I approach playing the arranger as a totally different instrument from a trad piano, so find 61 notes a nice balance to afford portability ease. Even if 76 notes could be accommodated in Tyros 4, it would probably add 8-10+ lbs more to its weight. I prefer the flexible option of simply taking along a 76/88 note keyboard controller on the those rarer occasions I'm required to play my Tyros 4 primarily as a solo piano. For arranger mode playing though, and as Joost clearly demonstrated, I find 61 notes quite adequate for that playing style. Don't forget, like an accordion isn't an organ, neither is a portable arranger keyboard an acoustic piano. They are each different unique instruments in their own right, so I approach playing each of them differently.
