That's correct.

I think Rosegarden is alsa native, where it can send depends on how it 
works internally. If it is a native sequencer alsa client and server the 
ports it offers will be listed (I think) by "acconect -l -i" and "acconect 
-l -o" once it is up and running. 

I believe the kind of routing you are asking about is not possible betwen
the oss (emulated) and alsa. I would ask alsa-devel, or the developers of
Rosegarden itself. Obviously if both apps use the alsa midi sequencer
interface the connection would be possible.
