I am remembering what Nigel told Tony. If you aren't interested in the KMA, and don't have one, and don't intend to get one, because you don't like the key size or for whatever reason, WHY keep putting it down, since it doesn't concern you?
Could it possibly be to promote the brand that you own?
Maybe it's just a long cold winter and there's nothing else to do?
There are MANY features on current Yamahas that employ technology well over ten years old; for just one, the awful vocal harmonizer.
