Sounds like something goes wrong at interrupted time.
Did the callback you pass to MPU401 create_device() call ever called?
Did the MPU401 interrupt_hook() is correctly called when a MPU interrupt raised?

Do you ask Jerome Duval some help? AFAIR, he managed to get some MIDI support 
in his emu10k driver project...

Oh, BTW, somewhere on the road, OBOS midi team will have to rewrite this MPU401 
kernel module too. Glup. ;-)
