Is there a way in fluidsynth to shift a whole soundfont up or down an octave? Or would I have to edit the soundfont in Swami and permanently move the notes around? -ken

You can use FluidSynth's MIDI router. For instance, type the following commands in FS' shell: router_clear router_begin note router_chan 0 8 1 0 router_par1 12 127 1 -12 router_end It transposes notes in channels 1 to 9 one octave down.

I tried this, and it did indeed shift the notes an octave down, but, it broke fluidsynth so that it doesn't respond to Volume or Expression CC's anymore! Is that a bug in Fluidsynth or am I doing something wrong? -ken

This is the expected behavior. In FluidSynth, "router_clear" deactivates *every* event, not only volume or expression controllers. I mean that after the following commands: router_clear router_begin note router_end FluidSynth will recognize notes, but not controllers or program changes, or any other message types. To activate controllers again, you need to execute the commands: router_begin cc router_end The same for program changes. You can restore them again with: router_begin prog router_end Complementary of router_clear is the command "router_default", that reassigns all the initial defaults (losing your custom rules).
