I might be wrong, but I don't think you can. The noteon and noteoff commands are more for testing and demonstration, the way to use fluidsynth is as a Midi device. You use a sequencer or hardware midi controller to drive Fluidsynth. If you wish to write your own midi files, I suggest you look into something like midge or abc2midi. These programs allow you to write notes in text, the latter using the ABC notation. If you are not particularly attached to midi, you can also use sound compilers like Csound, SuperCollider, or ChucK to accomplish the same thing with far greater control. Finally if you have a hardware midi controller, you can drive Fluidsynth directly, but it's far more convenient to use a sequencer like Midish. I should mention that I'm not very well versed in serious sound production, although I've tinkered a bit. However, I know that there are others on this list who do this sort of thing for a living, and they might give you a more comprehensive and/or accurate answer.
