[nathan at gandalf nathan]$ amidi -l
Device    Name
hw:0,0    EMU10K1 MPU-401 (UART)
hw:1,0    Mia  // This is interesting.  Dunno why this is in there as a MIDI 
device, it can't do MIDI at all.

[nathan at gandalf nathan]$ amidi -a -d -p hw:0,0
hit keys, wiggle wheel, change settings... nup... nothing...

Don't really have the gear to check that one.

Cool, so it probably isn't the source of the problem then?

As you can probably tell, I've also got an Echo Mia in the same box, and a 
US428 (MIDI works fine on that) sometimes hooked up externally.

Thanks for the help so far guys.
