This version will run in Cabbage. Note that it just plays the same note over and over, but perhaps you can tweak it to your needs. Instead of reading from a midi file it just triggers the playback instrument using events. Just make sure that you have the .sf2 file in the same folder as the .csd, the .sf2 file can be found in the Csound manual folder under examples.
