Good point Bebop! I always keep my midi files backed up on several different media and just transfer them to the keyboard. I don't think NX sound files can be copied to external media. I may be wrong, though. I haven't tried that, yet. I think the only files that can be loaded into the keyboard are SMF and Technics format. I have noticed some sound cards displaying the NX Sound format. I wonder if this is all the same. Does anyone know if other keyboards, other than Technics, have the NX Sound capability?
