MIDI (Musical Instrument
is a protocol that allows computers, synthesizers,
sound cards and drum machines to control each
other and to exchange system information.
Physically, it's an one-way (simplex) serial
current-loop connection running at 31,250 bits
per second and it requires five-pin DIN plugs for
MIDI-IN, MIDI-OUT and occasionally MIDI-THRU.
At the moment, blueMSX supports three kinds of
MIDI interface :
- Panasonic MSX-MIDI
- Yamaha CX5M/CX7M MIDI (SFG-05)
- Philips Music Module (NMS-1205)
The MSX-MIDI interface is only available on the
generic MSXturboR machine and on the Panasonic FS-A1GT.
The FM-BASIC can be used on these machines for
programs with MIDI music.
The SFG-05 interface is a cartridge that can be
inserted in a reserved slot of the Yamaha CX5M/CX7M
computers. With a little adapter, this cartridge
can be inserted in a slot cartridge of another
MSX computer. It has also FM capabilities as
Other MIDI interfaces can be connected on MSX2
and MSX2+ machines or on the Panasonic FS-A1ST,
for example the MIDI interface included in the
Philips Music Module. This cartridge has also MSX-AUDIO
capabilities as explained here.
The most used synthesizer with MSX computers was
the Roland MT-32.
In all cases, you need to use the Options/Sound menu
of the emulator. Check also eventually the page
about the Yamaha CX5M/CX7M computers.
MIDI sounds produces a stereo effect, that you
can enhance in the mixer.
A better sound can be obtained in the emulator
when you remap the MT-32 instruments to General
MIDI and/or when you use a special software that
