Yes.  Anything sent to the sequencer ports will show up (only!) on the
raw MIDI ports, and vice versa.

Anything sent to a through port will be routed to all other connected
ports.

The virtual MIDI ports convert between old programs using /dev/midi*
and new programs using ALSA sequencer ports.  They do not connect
ALSA sequencer programs together; use the through ports for this.

I think you can achieve what you want by connecting a virmidi port and a
through port together.
