Well, there's good news and bad news !

Using the compatibility facility, in both Windows 7 and Vista, Fred's SD_Explorer, SD Jukebox and the Panasonic Recorder all work OK. However, although I could Backup and Restore SD Card data using Song Manager and play audio files on a PC through the KN7000 sound system (as normal), I could not carry out Technics or MIDI files transfers via the USB link. This would be important to me since I normally always carry out file transfers this way, rather than using floppy disk. When I get time and my friend's PC is available, I'll try to investigate the problem further.
I was using the Home Premium 32 Bit version of Windows 7 on a Dual Core Processor PC and Vista Home Premium 32 Bit version, for the tests.
