I have successfully converted a couple of Yamaha 740 styles for the MZ-2000 by inserting them into my xg works sequencer, changing them to a standard midi file ( format 0 , and then introducing them into the 2000 via disk. I then used the "convert song to pattern" function and voila,....I have 740 styles on the MZ. They work fine there . It was a few hours of learning curve at first, as there are a couple of tricks I learned, but I can now convert a style in a few minutes. they work fine as well in the mz, except that there are only 3 fill ins instead of 4. Everything else is pretty much the same. At some point as my schedule permits, I will post these styles on a site like the great one that is on egroups.
