Try "cat /dev/midi???" with your device. This will output the incoming data as ASCII (i.e. garbage), but the garbage should appear at the same moment you press the keys on your MIDI keyboard. > 2) Valid MIDI files won't playback to external MIDI > instruments -- there is no sound output. Please try the midiloop program in the alsa-lib/tests directory with MIDI Out connected to MIDI In. > Is anyone working on a patch for rawmidi.c? On my machine (not a Soundblaster) rawmidi works, so the problem is most likely not in rawmidi.c.
