You wanna "java Main.class" to run the program.

Program will most probably say something like "midi input device not detected blabla, type a number" you should type 1 and press enter.

To create music you'll have to have some midi-piano plugged into your midi-port (if you have one). It may not work, i didn't tested with other device than my piano, but i don't really care.
