Hi John.
Since I'm one of the few arranger keyboard users who dont fancy the too
"machine" souding Yammie styles, I might as well be the first to reply.
I find the sound too clean, cold and polished, and styles is a kind of
too perfect. It don't sound "human" in my ears. Start the style and it
sounds the same level whatever style I hear,a kind of limited in peak.
If I did not feel it that way, I would probably been a Tyros owner long
time ago......
If you i.e. listen to Ketron SD1 or SD5, the bass and drums give a very
live feeling, and when swap styles, it don't sound like it's a totally
different orchestra playing, it give me a feeling of that's the same
"gang" playing.
The nearest I've heard who manage this, is so far Korg.
But again, as said before, this is very personal, just the way I hear it.
Happy Playing whatever keyboard we play on
