Hi Pro: I'm with YOU here regarding the acoustic piano sample being one of the most important factors in choosing a kb. Yamaha acoustic grand pianos have never been my personal favorite sounding pianos. Yamaha pianos sound a bit clinicaly clean sounding (lack of enough rich harmonic overtones, and a bit shrill in the upper registers) for my taste, but I did find that (at least from listening to Simon's MP3 demo) that the Tyro 'live' Grand sounds sounded much better than I expected, for a Yamaha type piano sound that is, especially when played along with auto accomp parts (drums/bass). In the meantime, I'm also VERY interested to find out how the Tyros piano compares to the 9000 Pro and PLG150-PF piano samples. Pro, knowing what a discrimating musician you are, I look forward to hearing your findings. - Scott
