SynthGuy. The boundaries of possibility are only limited by the spirit of man's imagination. As much as I like & appreciate the features of my Yamaha Tyros, I still see areas that it (as well as other current top of the line arrangers) can and will eventually be improved upon. This includes continuing sound quality advancement which will be achieved when overcoming storage capacity limitations. The next step is attaining the new SACD (super audio compact disc) quality 'sampling rates' which will more accurately & realistically reproduce acoustic instruments, especially the acoustic piano. In the area of auto accomp styles, implementing new SMART technology which will more intelligently vary accomp style pattern playback & more realistically reflect the kind of expressive real performance subtlies played by live rhythym section musicians.

Arranger specific keyboards have only recently garnered serious interest from pro musicians because arranger keyboard manufacterers are finally listening to their needs, of which not only include more realistic sounding instruments & styles, but the arranger's ability to now allow one to play the keyboard in the way they've been accustomed to playing both solo & with a live band, utilizing genre specific types of pro chords & licks

The arranger keyboard is the marriage of computer technology with the traditional keyboard, and as long computer technology advances & improves, so will arrangers and synthesizers. My acoustic Steinway Grand piano is my ONCE in a LIFETIME investment, afterall, the acoustic piano had over 100 years to evolve & perfect. I EXPECT to eventually upgrade my Tyros (which I've owned for 2 years now) whenever a substantial arranger keyboard improvement comes along to warrant it, and it WILL, trust me. -Scott
