Glen,
I did not find the KN7000 Midi friendly, there is much to learn. If #10 are drums on the Midi file and #10 is piano on the KN7000 you will need to revoice the instruments.

It has been a while since I worked with midi but there are some very talented men on this forum that can help and explain.

No, you did not waste your money, you just bought a tool that will help you to learn.
