However, for many of you with greater skills, the Tyros' ability to overwhelm you is an obstacle, not a benefit. You want to sound like YOU, not a Tyros.......... You want to sound like a band, NOT a CD..........

Fair comments there, most arranger keyboards especially when using the latter variations can have far too much going off in the accompaniment department to make the styles unuseable, however as with all arrangers you can simply edit the styles or create your own registrations etc so the song you're playing contains as much fancy backing as you the user permits.
I've edited all of the sounds and styles that I use so I have customised my Tyros 2. I know what you mean by saying you want to sound like you and not a Tyros. 2 people who I listen to when I get the chance use the same Tyros 2 presets and other than their different playing abilities sound almost identicle, it gets boring after a while just listening to them.
Each individual should always customise their instrument and develop their own style of playing. What is the point of being a carbon copy of someone else? I loved Vangelis and Jean Michel Jarre when I was young but there is no way I ever wanted to play like either of them, even though I can play all of their songs. I'm perfectly happy with the way I play and always will be. As long as you all continue to enjoy making music it doesn't matter how it's performed, how skilled you are, or what instrument you use. It's when you stop enjoying what you're doing when you should start to worry
