So the virmidi module itself is loaded and working.

I don't think that tool is usually packaged.
There's the command-line tool aseqdump.

This is not how virmidi is supposed to work.

The purpose of virmidi is to interface programs that use OSS raw MIDI
devices (/dev/midi*) with programs that use ALSA sequencer ports.
This means that anything sent to /dev/midi1 will be output from port
20:0, and anything sent to 20:0 can be read from /dev/midi1.

If you want to connect multiple ALSA sequencer ports, then
1) just connect them directly, or
2) load snd-seq-dummy and use the "Through" port.
