You don't seem to have any midi driver loaded. Check if ALSA has midi support for your soundcard. If not, you can use either timidity or fluidsynth to simulate midi sound but both need much cpu power.

Might wanna try setting config=63:0 under the midi section in the config file and setting the device=alsa

Yeah, looks like ALSA doesn't support midi on my chip yet. 😒
How do I get timidity to work with dosbox - I can't seem to see anything in the man page or README file. I have timidity all set up and working (as in I can play midi files)

Thanks!

Execute it with "timidity -iA" then it becomes an ALSA server at port 128:0. You have to set the port in the dosbox config file.
note: timidity will be more accurate if it is run as root.
