Tooling around on the command line I noticed that MidiLink is trying to use serial USB instead of the Roland interface. There is this file: /tmp/ML_SERMIDI that seems to force USB serial. If I delete that file, MIDI stuff starts working again. I don't even have to restart MidiLink, it just works fine after that.
The issue is that that file comes back every time I turn the Mister back on. I'd like to say it "just stopped working" but I had not tried the MIDI stuff in 2-3 weeks so maybe something happened within that time that crunked it.
I have the ao486 core set to:
UART mode(MIDI)
Connection: MIDI
MidiLink: USB
Baud: 31250
The only issue seems to be that file mucking up the works. I trash it and everything works fine as usual. Any ideas? Has anyone come across this before? Searching the forums for "ML_SERMIDI" yields nothing.
EDIT
I did a little bit more investigation and it looks like the ML_SERMIDI file doesn't get created until ao486 is started.
EDIT #2
If I run "midilink" with no arguments while the core is running, MIDI works fine.
If I run "midilink MENU QUIET" like the core seems to do I get:
/root# midilink MENU QUIET
midilink: /lib/libasound.so.2: no version information available (required by midilink)
