I have to say that I love my 9000pro.....

....BUT of all the keyboards I've owned the one that MOST impressed me with SMF playback was the Roland EM2000. Don't know why or what it was that made it sound like it did but boy that board could play midi files!

Pity it never sounded quite the same when I played it

Also Mike, Excellent idea but unless we all played the same file on the same board through the same sound system we would all get massively different results.
Best to you all
