WHY'S THIS USEFUL?

Games from the late 80s and early 90s that support music via the Roland

MT-32/CM-32L often expect to find a hardware MPU-401 interface that supports
'intelligent mode'. These are now expensive and difficult to find.

By supporting the 'intelligent mode' features in software, these games will
work with the basic MIDI interfaces found on sound cards.

REQUIREMENTS

- EMM386 4.46+ (MS-DOS 6.2) or QEMM 7.03+ must be loaded
- Sound Blaster (or compatible) sound card
- Roland LA synth (e.g. MT-32, CM-32L) or a sound card with MT-32 emulation
- EMM386 4.46+ (MS-DOS 6.2) or QEMM 7.03+
- Sound Blaster (or compatible) sound card (MPU-401 & SB-MIDI mode)
- Serial port (Serial MIDI mode)

USING SOFTMPU
USING SOFTMPU: MPU-401 & SB-MIDI MODE

Run SoftMPU specifying the base I/O port address and interrupt of your Sound
Blaster, and the base I/O port address of the MPU interface, e.g.
Run SoftMPU specifying the base port address and interrupt of your Sound
Blaster, and the base port address of the MPU-401 interface, e.g.

SOFTMPU.EXE /SB:220 /IRQ:5 /MPU:330

The optional /SBMIDI switch forces Sound Blaster MIDI to be used. This mode
is intended for use with the Sound Blaster Pro 2 and other sound cards
without a hardware MPU interface. Game compatibility may be reduced.
The optional /OUTPUT:SBMIDI switch forces Sound Blaster MIDI to be used. This
mode is intended for use with the Sound Blaster Pro 2 and other sound cards
without a hardware MPU-401 interface. Game compatibility may be reduced.

USING SOFTMPU: SERIAL MIDI MODE

Run SoftMPU specifying the serial interface to be used and the base port
address of the MPU-401 interface, e.g.

SOFTMPU.EXE /MPU:330 /OUTPUT:COM1

A Sound Blaster base port address and IRQ can optionally be specified if
MPU-401 interrupts are required.

FURTHER OPTIONS

The optional /DELAYSYSEX switch enables small transmission delays to prevent
buffer overflow with the Rev.0 MT-32.

Problem: Some games expect to find an MPU interface on IRQ 2, but my sound
card doesn't support it.
Solution: Use IRQ 9 instead. This is supported by Yamaha YMF71x sound cards,
maybe others too.
Solution: Configure your sound card to use IRQ 9.

Problem: SoftMPU can't find a hardware MPU interface when using a Sound
Blaster Pro 2 or older sound card.
Solution: Run SoftMPU with the /SBMIDI switch.
Solution: Run SoftMPU with the /OUTPUT:SBMIDI switch.

Problem: My Rev.0 MT-32 displays "EXC. BUFFER OVERFLOW". Music playback
sounds incorrect.
