.TH DMID 1 .SH NAME dmid \- MIDI to OPL3 converter using GENMIDI-type instrument banks .SH SYNOPSIS .B dmid [ .B -2 ] [ .B -i .I bank ] [ .I file ] .SH DESCRIPTION .I Dmid decodes MIDI instructions either from .I file or from standard input, and produces .SM OPL3 instructions suitable for playback by .IR opl3 (1). To program instruments, an OPL2 instrument bank formatted as .SM GENMIDI lumps from .I doom must be provided. Since it is assumed that the bank is contained in a .I doom WAD file, its default location is .BR /mnt/wad/genmidi . This may be overridden with the .B -i command line option. .PP In .SM GENMIDI lumps, two voices are defined per instrument. For compatibility, the .B -2 flag disables the second voice, reducing the number of .SM OPL channels needed. It also disables .SM OPL3 specific features and produces an IMF-format stream, which can be used in other game engines. .SH EXAMPLES Play a MUS file from a .I doom WAD file: .IP .EX % games/wadfs /sys/games/lib/doom/doom2.wad createfile SW18_7: file already exists % games/mus /mnt/wad/d_doom | games/dmid | games/opl3 >/dev/audio .EE .SH SOURCE .B /sys/src/games/dmid.c .SH "SEE ALSO" .IR games (1) , .IR mus (1) , .IR opl3 (1) , .IR audio (3) , .IR wadfs (4) .SH HISTORY .I Dmid first appeared in 9front (July, 2018).
