this is strange. It simply works for me (tm).

What versions did you try? (jackd, rosegarden...)

I see.

That's what I was thinking :)

I think, aconnect (part of media-sound/alsa-utils) is the tool you want to 
try.
Start both rosegarden and zynaddsubfx, then use aconnect -lio to see, what in- 
and out-ports were created on your system. After that use aconnect to connect 
the rosegarden out-port with the zynaddsubfx in-port.
http://alsa.opensrc.org/Aconnect has some details.
I never tried this for myself, so I have no practical experience with it.
