That last sentence confuses me.  When you say "in the sequencer 
configuration section", do you mean it's listed as a command-line 
option in the sequencer section of the Rosegarden GUI's configuration 
dialog?

If so, that would be quite strange, because the Rosegarden sequencer 
doesn't expect that argument at all. (It's a familiar option to me 
because fluidsynth uses it, but Rosegarden won't understand it.)  Try 
removing it and starting again.

That aside, the usual way to resolve problems of this sort is to try 
running the "rosegardensequencer" binary from the command-line on its 
own, without running the GUI.  It should print more diagnostic 
information that way.  If you still have trouble with this, perhaps 
try asking on the rosegarden-user mailing list.

With Rosegarden, you should be able to simply select any running 
alsa-sequencer-interface-driven soft synth as an output wherever you 
like.  Rosegarden doesn't host synths for you, it just talks to any 
that you have already running (or that you start up while Rosegarden 
is running).  The synths themselves (timidity, fluidsynth, 
zynaddsubfx etc) can generally produce output either directly or 
through JACK; the former obviously limits you to running one at a 
time, but it's simpler for initial diagnostic purposes.  Either way 
you will probably need to disable aRts.
