fluidsynth only allows to render midi channel(s) to dedicated audio channel(s), the so called multichannel-rendering. To me your problem of note-to-audio-channel-rendering sounds very custom and I cannot think of a way integrating this feature into fluidsynth without making synthing and mixing more complicated, memory-hungry and exposing more complexity via the API to the user. I think this problem is best to be solved by using fluidsynth's API to interfere the midi events and keeping track of the note on / off events that are sent to the synth by modifying the midi channel of those events accordingly. new_fluid_midi_driver() and new_fluid_midi_router() allow you to specify your own custom midi processing function that could take care of that. Finally you would need to pull out the audio using fluid_synth_nwrite_float(), that would give you the separate stereo outputs rendered for midi channels 1,2,3,...
