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. + diff --git a/doc/08.tex b/doc/08.tex index 56e829415d..84cdf3285f 100644 --- a/doc/08.tex +++ b/doc/08.tex @@ -102,11 +102,15 @@ The following keywords are recognized: & supported by some MIDI drivers.)\\ native\_mt32 &bool If true, disable GM emulation and assume that\\ & there is a true Roland MT-32 available.\\ + enable\_gs &bool If true, enable Roland GS-specific features to\\ + & enhance GM emulation.
