Great, so CPU load can be managed easily.

I tend to agree since you could rout the audio signal from fluidsynth
--> jack_rack + LADSPA plugin --> jack audio output port

Considering lv2, I am not aware of lv2 support in Jack-Rack though it is
rumored that this support is planned. Since the lv2 implementation is
supposedly more robust than LADSPA [1], it could prove to be an asset to
FS.

Markus? Would you agree ?
 
Perhaps, Josh has another take on this.
