A cool thing I just saw was when you enter channel on/off like in older models you see your 8 tracks within the style including the 2 rhythm tracks, and when you push the channel on/off a second time you see just 3 tracks, "rhy1, rhy2 and audio trrack". You can turn each one on or off. With some of the styles you might have the bass drum and closed high hat played by rhy2, percussion on rhy1 and the snare and cymbals on the audio track.
Larry, what I noticed about the audio styles are how Yamaha has been able to create drum tracks that are recorded in different environments and with different mics, etc. The two audio styles in the "pop and rock" section are done with the 1960's live sound highlighted. It's very much just like if you heard songs recorded back then. When you go into the live styles in the R & B section they sound like those "in your face" kit sounds I've been waiting for Yamaha to do for years! The latin and swing and jazz audio styles are top notch and there are a few middle eastern styles that Yamaha has nailed! I wish there were more but in speaking with the product manager for this division today I am sure Yamaha will release more over time.
