Ok let me explain a bit more.
Say you download a midi from the internet onto your computer and pop it into a floppy disk and then take that floppy disk over to your KN7000.
You then with the KN7000 can load that midi file onto the screen and in the process of loading it you will see some options on the lefthand side of the screen called 'load as' options.
Select GM/GM2 - NX from those options and your midi will be recognised by your KN7000 as a technics file rather than a midi file although it remains a midi file. When you then save it to an SD Card you save it as though it was settings for a technics style file rather than a midi.
Following this you are able then to put that file into your favorites area.
Hope this helps in relation to KN2600 as well.
