Upgrading from a PSR3000 to the Tyros2 I have to agree completely with Tapas' comments. I don't know if it is the instrumentation of the styles, but balances of all the voicing/mix is perfectly blended. The subtlety of each instrument is just right. Whatever Yamaha did to the Tyros1 styles that they tweaked for the Tyros2, somebody spent some real time and effort to make them sound so good. It's not just the SA voices either. I've played many Tyros1 premium pro styles I've had and many of them just seem to shine. When I finally got this keyboard I didn't see why it cost twice as much as the PSR3000 I loved. But after playing it for a month and downloaded some of the premium (and non-premium!!) styles using the IDC connection I am so glad to own it. I have never played anything that has made ME sound so good. Just another subjective opinion..........................-charley
