this was written for the openmpt fm+pcm (though i didn't use pcm) example compo. it didn't get in unfortunately! I know i'm not supposed to submit stuff that has been released, but i wouldn't really call the file that you can find in a .zip download with other files somewhere on s3m.it without a name tied to it a release, so i'm submitting it here!
dit: Open in OpenMPT because it uses MPT hacks. It's still a valid adlib entry, as OPL playback is what is important, not Scream Tracker 3 playback.
