That is quite an involved assessment, and, I'm sure, generally correct. As far as midi is conscerned,I too, prefer it. I do a Wednesday keyboard and Karaoke show. I have plenty of CD&G disks, but when I want the crowd to dance, I use good midi's or the G70. For some reason the CD's don't stir them to dance, nearly as well. I suspect it is compression. In fact, the only reason I prefer CD's on occasion, is backgroung vocals.
