This is a "raw MIDI" port, which is what the hardware drivers implement.
Application ports and merging are implemented in the ALSA sequencer on
top of that.
VP does not show up in qjackctl however and once
connected to the HDSP
I can no longer make a connection between the UMX490 (readable client)
and the Hammerfall DSO (writable client) in order to play the synth.
The HDSP seems to be fully occupied.
When a program uses raw MIDI directly, these features are not available.
As a workaround, load the snd-virmidi kernel module, which creates
virtual raw MIDI ports that are then available as sequencer ports.
Connect VP to that, and then connect snd-virmidi's equivalent sequencer
port to the actual device.
