Glad to finally find these excellent demos posted on the web by Yamaha. Thanks to UK artist Andy S. for his fine 'live playing' performance skills, especially on the impressive solo sax & guitar demos. Btw, the impressively realistic 'breath effect' on 'S.Art Sax Saxophone' & 'guitar noise' on 'S.Art Guitar' are triggered "live" as well: via assgignable foot controller, of which is a KEY feature of "Super Articulation' voice playing. In addition, playing "Super Articulation' voices normally on the kb, automatically delivers expressive finger slides to guitar sounds, breathy legato phrasing to saxophone sounds, or a range of bowing effects to string instruments. Tyros2 utilizes complex algorithms to determine which sample (there are multiple sound samples per each note) is played, and determined by the velocity (how hard you hit the note), playing speed, and the interval distance between the notes. This imo is a very exciting keyboard advancement adding even greater realism to acoustic instrument emulation. Another PLUS with Tyros2 is that MusicFinder is no longer limited to only accessing USER Memory Styles. I also appreciate the addition of recording audio, yet it's limited to only 2 audio tracks. - Scott
