Hi Peter,

Since I don't actually own a KN6000 keyboard myself (lucky me?) as I still have a KN5000, I'm not certain I'm on the right track, but here is my thought for what it's worth:

After loading the KN5000 composer style into the KN6000's composer memory, you may actually need to re-save it as a "KN6000 format" composer memory file onto a floppy diskette and then re-load this file back into the KN6000 before the file can be successfully transfered to the KN6000's Custom Memory.

Hope this helps.

- Scott
