Funny, but I clearly recall hearing Nielshs music and being 'very impressed' with both his performance & the sound of his (Roland G70?) keyboard.
I don't recall a SMF being used, but instead, performed in auto accompaniment mode.
Nielshs, perhaps you can re-post your song(s) again. I for one really 'enjoyed' it.

Though I don't agree with Nielshs' assessment about Tyros 4 (afterall, I do own one and love the sound),
since he owns/owned both a T3 (but not a T4 ) and G70 at the same time, I respect his personal opinion, albeit bluntly presented.
Frankly I could care less what fellow members prefer or play, but instead admire what peope can do on the instrument they actually play.
As Montunoman stated in his sig: It's not the keyboard but the keyboardist that matters the most.
