Back when John Paul Jones joined the US Navy, I originated Gig Disks right here on this site. And, I used the same technique that Toril described, renaming certain style files that fit nicely to a song, then modifying those styles to make them unique to the song. Back then, I was using a PSR-740 and saved them on a floppy disk, hence the name Gig Disk. Each disk held about 30 style files.
Someone later came up with an idea about naming registrations gig disks, and I think it was Hammer (Deane Peters). Deane would create a number of registration banks and name each bank with a song name, then store them all in a single folder for certain performances.
Both methods work, and work well, especially when used in conjunction with third party style files, and with the newer keyboards, those third party style files can link from the USB drive to the Music Finder Directory, which is a bit plus.
Good luck,
Gary
