Hi, I am in a hurry, but this is a good program to convert .Kar to .mid, and vice versa, the thing is that this is a shareware programe and it is for evalution only so it is suppose to work for anout 5 days, but if you clean everything up and re install it it will work.
This is the site to download it from: http://www.gnmidi.com/

Enjoy.
Tony.
