2 or more dlls using the same exported function.

I have a control surface plugin dll for an audio workstation.
The workstation only allows a plugin to be connected to one midi port for in and out.
So to support more than one of these control surfaces I made a very simple version of the primary dll plugin that forwards midi messages from it's (second) port to the primary plug in dll for processing. So I load the primary dll for the 1st unit then the smaller I/O re-director plug in for the second unit. It all works great. The two dlls communicate via exported functions for message exchange.

I want to be able to load yet another I/O redirector dll for yet a third or even a forth unit on other ports but would like the DLLs to be generic and not specific to the ports.

My question is: What happens when you load the same COM DLL in the same process space and the same function exports for incoming data?

When I examine the exported functions of my dlls when loaded in the DAW app exe file I only see the exports for one "instance" of the exported function in question.

Will I be able to magicly call the same function on both DLLs simultaneously?
Probably not. I'd like to do something like that.
