I downloaded MIDI OX and it works fine. In fact, it's a formidable programme; something tells me that if I ever learn to use it properly, I'll be using it a lot. I hooked up the EMU to the computer via a Yamaha USB-to-MIDI cable, selected it as an output, loaded the files (which loaded fine), and apparently sent the files out successfully. However, the EMU unit remains unchanged. The titles are still scrambled, and there is still no sound. Is there something in particular I need to do with the EMU while I'm sending out the sysex files, some sort of input mode or something? I can't figure out why it's not working.
Thanks again for your help
