its not a "server process" per se, but timidity will render midi->PCM,
and then you can run the encoder of your choice. because (1) this is a
unix-like operating system and (2) just about every tool you can think
of is available at no cost, there tends not to be a single
monolithic program to do this. it would be more typical to use other
tools, such as shell scripts and so forth, to link existing tools
together.  for example:

	   #!/bin/sh

	   timidity $1 && oggenc $1.wav && rm -f $1.wav

more work would be required to point timidity at the desired
samples/soundfonts you wanted to use. of course, if you are talking
about trying to use a VST/i, its a whole different story.

you haven't defined what kind of plugin you mean. for LADPSA,
applyplugin will do the job. for VST, we haven't written such a tool
yet, but its less than a day's work to get a cmdline tool for that working.

i can't imagine what that would mean, to be honest.
