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.

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.
