Thanks all of you for quick reply.
Bernie9 and Larry:
- The SD is already formatted (can be done on KN7000 or SD-Jukebox). The midi's from Yamaha are in GM format and can be read by KN7000 and store on SD card. That i know. The ball game is renaming them again using the KN7000 instead the PC. Basically, I didn't know that SD Explorer does not handle midis.
Technicsplayer: Thanks for your expertise - that I didn't know (as always you're the guru)!!. Anyyway, looks like I have to go w/Techmanager7000 (not cheap!!!).
