+The container has ffmpeg, mikmod (for screamtracker modules), timidity (for midi files), and LAME (for encoding screamtracker and midi files to MP3).
+Subsonic is not, by default, configured to use mikmod or timitidy. You must add the configuration. In the transcoding section, add a configuration like
+the following for screamtracker / etc files:
+
+| Name               | Convert from                                                               | Convert to | Step 1             | Step 2                                                                  |

+The `mikmod_stdout` and `timidity_stdout` scripts are simple scripts that run mikmod and timidity sending
+the output to stdout in wav format for lame to use for encoding. If you have no need to handle tracker or
+midi files than you can safely ignore this configuration.
