I wanted to produce a video showing the tracker interface as it scrolled
through the score while playing the song, using the same tracker that
was used to compose the song.  My first attempt was using FastTrackerII.

My problem was that VirtualBox advertised SoundBlaster emulation, but it
doesn't work at all in DOS.  Analysis from others leads me to believe
that it is VirtualBox's fault.  I tried running FT2 and others in DOSBox
but the performance was so slow that it caused audio skipping.  So what
i ended up doing was using xdotool and VBoxManage to coordinate the
tracker playback, capturing video with ffmpeg, and then muxing in the
audio track produced previously by the tracker's disk dump feature.  I
may have had to trim the audio track with sox before i got it to sync.

I'm done playing that game, so i don't really have anything to prove.
But feel free to have a go at it!
