I agree with you completely. Sound is always a matter of taste.
But there's a truth in saying the demo we've seen on BK9 is less than breath taking.
To me, I like Korg sounds better, but I do prefer Roland styles - that is why I am curious and interested on this new offering.
The biggest mistery to me is why would they add the mic input, with reverb and all, but not the harmonizer... Or, why put the mic input if not onboard speakers?... Does not make sense to me. What is gained? You either have to take with you the VH box, or the amp speakers. Or more likely both. What is gained? Maybe they believe this was necessary so that people can record their voice together with the instrumental...
