Al, first of all, congratulations on getting Tyros 4.

Though I don't use nor tried playing a SMF on my Tyros4, good to hear that, with a little re voicing, they can sound pretty decent. Nice vocal delivery but your mic trim (too hot) is distorting, especially bad around: 1:13.
Al, anxious now to hear more thoughts and perhaps a review from you on Tyros 4.

PS: Tony, I believe Al is demonstrating 'revoiced' SMF playback, with himself singing along to it only (not playing keyboard).
