Lee et all: Just got home from my gig with the Tyros 4 and as usual had the audience in awe with the sound, and believe it or not, particularally the style's background vocals, which I enjoy augmenting with my live lead vocal. I'm always getting comments asking where my backup singers are hiding. When I initially bought my Tyros 4 I thought I'd never use styles with vocal auto accomp parts, but I've since changed my mind. As a singer, I'm finding both vocal auto accomp and/or the ability to "live play" the vocal voices either in left hand (pad style) or as fills/solo in my RH a terrific way to add interest to my songs. The solo SA2 instrument voices sound equally impressive but it seems the backup vocals are wowing my audience most. My only Tyros 4 "beef" is the odd mod wheel direction assignment on organ voices, and the inability to call up reg bank files from the MusicFinder. Having my Tyros 4 for nearly two months now, perhaps the thing I enjoy most is It's out of the box impressive sound requiring little or no tweaking, and it's intuitive navigational interface, making This keyboard such a fun to "play" station vs "work" station.
