Summary:                    MIDI I/O (MPU-401) works for output only, not input
Description: 
I have a Sound Blaster PCI 512, and MIDI interfacing with external devices,
such as keyboards, only works for output (from the soundcard to other
devices). When I try to do input (from those devices to the soundcard) no
events get through at all.

The single irq is used for all pcm and midis.  So, don't run any audio
program during you measure (even better on console rather than on a
graphical desktop system to avoid beeps per PCM).

And, are you sure that the midi device produces a right MIDI byte stream? 
Can it test with a loopback?

The device works properly with input on a soundcard in another computer
(that one uses the snd-cmipci driver), so I'm positive it's functional. I
can even use aseqnet to run the input to this system. However, it's a
royal pain maintaining an entire second system just for MIDI input.
