Also new is Roland giving several of us what we have been asking for, a G-1000 with vocal harmony and SRX expandability. Yamaha has given us an expandable 76-key aranger with vocal harmony (9000Pro), but specifications are not everything. Roland instruments have a different character than Yamaha instruments. It is not a matter of one being better than the other, but I just prefer Roland's approach to sound programming.

Also, my guess is that Roland's adaptive chord voicing is not so much a more sophisticated chord recognition scheme, but a more flexible approach to implementing the chords it recognizes. For example, if a player plays Cmaj in first inversion closed vocing and then plays Fmaj in first inversion closed voicing, if the arranger follows this, there would be generally awkward sounding parallel fifths. However, adapative chord voicing might switch the F to second inversion to avoid parallel fifths and provide a smoother transition between chords. It is "adaptive" in that the way the Roland plays a chord depends on the chord that came before.
