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.
