I'm not sure what you mean here. I've attached a variety of reports to
the end of this message, perhaps you'll see something significant there.

>What do you want to do that the through ports cannot do?

I use Xsteem and Dosemu to run various MIDI applications. They want a
direct link to the device, and linking to /dev/snd/midiCxDx gives me the
greatest flexibility. It would be much better if they abided by the ALSA
convention of indicating devices (hw:x,x), but they don't.

Best,
