Adding the following command provides a way to convert MIDI > code to sound using Fluidsynth:
Redirecting two ports to midithru/0 is supposed to work: $ midicat -d -q midi/0 -q midithru/0 # in one terminal $ midicat -d -q midi/1 -q midithru/0 # in another terminal should merge the two inputs. Both terminals should show the events of the corresponding input. If there's a synth on midithru/0 (ex. fluidsynth command below is running) it will produice sounds for both inputs. > > $ fluidsynth /usr/local/share/generaluser-gs/GeneralUser_GS.sf2 > > However, this only works for midi/0.
