Note: This new MIDI support requires FS-UAE 4.0.0 or newer.
You currently need to specify the MIDI device you want to connect to using the
serial_port option and the "name" of the sequencer, like this:
serial_port = midi:<name>
Note: The method of configuring MIDI and/or choosing MIDI device might change in future versions of FS-UAE!
Finding the MIDI device name
You can list the midi device names with fs-uae-device-helper:
If you are using FS-UAE Launcher, you can go to Prefs -> MIDI and this will also list the MIDI device names for you!
Using Munt for MT-32 emulation
mt32emu-qt from Munt on Linux, use option
serial_port = midi:Standard
to enable MIDI output via emulated serial port and route to the ALSA sequencer
set up by mt32emu-qt.
On macOS, the MIDI device is different, so you can use the option
serial_port = midi:Mt32EmuPort.
On Windows, yet another name is used:
serial_port = midi:Mt-32 Synth Emulator.
But double-check that the device name is correct for yor system. See the section "Finding the MIDI device name".
You can run
acconnect -o to give a listing of ALSA MIDI sequencer names.
Example output while having both fluidsynth and munt/mt32 running:
client 14: 'Midi Through' [type=kernel] 0 'Midi Through Port-0' client 128: 'FLUID Synth (11883)' [type=user,pid=11883] 0 'Synth input port (11883:0)' client 129: 'Munt MT-32' [type=user,pid=11907] 0 'Standard
The names you need to use with the
serial_port option with this exact setup
is 'Synth input port (11883:0)' and 'Standard'.
Note, you can now also use
fs-uae-device-helper list-portmidi-devices to find
the device names.
The default fluidsynth sequencer name on Linux includes the process PID, which
will change each time fluidsynth is started. It is a good idea to run
fluidsynth with a static name, for example
fluidsynth -a alsa -m alsa_seq -l -i /usr/share/sounds/sf2/FluidR3_GM.sf2 \ -s --portname=Fluidsynth
You can then use the option
serial_port = midi:Fluidsynth.
Suggestions for future improvements
Split midi device name out from the serial port option?
serial_port_type = serial|midi|midi-mt32 ? midi_device = xxx ? midi_mt32_device = yyy ?
