No, this is the original midi. Actually, this is a commercial midi and it came in different versions: GM, G2... and some for Roland and Tyros keyboards; and some in SMF 0 format, and some in SMF 1 format.

I just thought the XF format would be a good one to try first.

I never quite understand all the channel names. I also a few other midis which has drum track labeled as acoustic piano. But all the other midi player do play them correctly as drum including the midi I sent you.

Yes, I will do that when I get home tonight.
