1) The KN2000 can read only Type 0 Midi file. You may have Type 0 or Type 1. If you have Type 1 you receive an error from the KN. You can convert from Type 1 to type 0 on the computer with a Midi program.

2) All instrument Midi compatible should play any source of Midi. The only thing is the Type (1 or 0). All the Technics Keyboard like the KN5000 or before was able to read only Type 0 Midi file. Since The KN6000 they can read both type.
