 Use the appropriate -e<mode> command line option from the list above to
 select your preferred MIDI device. For example, if you wish to use the
 Windows MIDI driver, use the -ewindows option.

+\subsubsection{Using MIDI options to customize Native MIDI output}
+ScummVM supports a variety of MIDI modes, depending on the capabilities
+of your MIDI device.
+
+If --native-mt32 is specified, ScummVM will treat your device as a real
+MT-32. Because the instrument mappings and system exclusive commands of
+the MT-32 vary from those of General MIDI devices, you should only
+enable this option if you are using an actual Roland MT-32, LAPC-I, CM-64,
+CM-32L, CM-500, or GS device with an MT-32 map.
+
+If --enable-gs is specified, ScummVM will initialize your GS-compatible
+device with settings that mimic the MT-32's reverb, (lack of) chorus,
+pitch bend sensitivity, etc. If it is specified in conjunction with
+--native-mt32, ScummVM will select the MT-32-compatible map and drumset on
+your GS device. This setting works better than default GM or GS emulation
+with games that do not have custom instrument mappings (Loom and Monkey1).
+You should only specify both settings if you are using a GS device that
+has an MT-32 map, such as an SC-55, SC-88, SC-88 Pro, SC-8820, SC-8850, etc.
+Please note that --enable-gs is automatically disabled in both DOTT and
+Samnmax, since they use General MIDI natively.
+
+If neither of the above settings is enabled, ScummVM will initialize your
+device in General MIDI mode and use GM emulation in games with MT-32
+soundtracks.
+
+Some games contain sound effects that are exclusive to the Adlib soundtrack.
+For these games, you may wish to specify --multi-midi in order to combine
+MIDI music with Adlib sound effects.
