As mentioned, it's no event router. Suppose you connect App A ->
virmidi and virmidi -> App B. Then the event flow is:
App A -> VirMIDI -> /dev/snd/midiC*D*
_and_
/dev/snd/miciC*D* -> VirMIDI -> App B
That is, there is no connection between Apps A and B.
If you need a static event router, you can use snd-seq-dummy module.
