There is a test application which shows all received events in the
alsa-lib source package. Go to the alsa-lib/test/ directory, run
"make seq", then call it like "./seq decoder 64.0", where 64.0 is the
client/port number (you have to use a point instead of the usual colon
here).

However, MIDI input on that card is broken AFAIK.
