o run an install this thingy you’ll need a working MIDI configuration and without JRE 5.0 (1.5.x) or better you won’t get it working at all. If you have all that it’s sufficient to load the jar file with the magic words
java -jar JRackAttack.jar. If you want to have a look at the sources get the zip file.
