I have downloaded and saved a .wav sample to floppy. I checked the disk on my PC. It's there and it plays fine. However when I put the floppy into my WK4PS2, and go to load sound, it doesnt even show that the file is on the disk. My instrument works fine and loads samples that are on the hardrive and when I saved them on the same floppy. The format of these samples I might add is .txl
I thought it could load .wav and other filetypes. What am I doing wrong and how can I do it correctly?

Thanks!
