Hi Tom,

I don't think your KN5000 will load KN6000 MSP files or indeed any other files from that keyboard. Before the KN6000 saves files it compresses them in a way that only the KN6000 can restore. Compression improves loading speeds but because Technics are keeping the process secret all Technics format files are effectively strongly encrypted and no software is available to unscramble them.
So unfortunately KN6000 users are isolated and cannot share their files with you, only among themselves.
