I was under the impression that the Roland did have a vocal harmonizer. I had heard that the Kork arrangers were very complex and hard to use...any comments on that? Also, which keyboard offers more STYLES per TYPE OF RYTHM. For example, if I play 6 songs with a Meditteranean rythm, I don't want it to sound like it's the same music with a different melody...Do any of them offer more than one style per type of rythm?

Thank you once again,
