i did the that to my psr 1000 . it used floppies. so i bought and installed a usb floppy emulator. i used a 2 gig usb thumb drive. partitioned it into 99 1.44 mb partitions . now all my styles, registration, smf's are in one place. no more switching floppies. so in reality i only need (1.) 40 or so styles to perform (2.) easy access to midi files. so i don't really need alot. this seemed to work well for me on an old outdated machine.
