Thank you for replying. I already searched a lot around the web for a 
good MIDI library. I found PortMidi which I think is pretty good for 
handling low-level Midi I/O. However it lacks support for MIDI files. 
And the problem is there : I need to play MIDI files while being able to 
dynamically modify parameters (tempo and velocity). Moreover, I need to 
play them on a Midi port (Midi synthetizer of the sound card, maybe 
external devices later). There are libraries on the web for loading Midi 
file but I don't know enough about Midi to handle the timing myself. 
Then, finding such a library is pretty though. I think that another way 
to do it is to use libkmid under Linux and DirectMusic under Windows... 
which complicates the task.

So, I will look at the source code to try to redirect output to a Midi 
port (I guess I should say "hack the source code" because it will cause 
fluidsynth to do something it wasn't developped for). I'll tell you 
about my progress about it even it it's not the main purpose of the lib.

Anyway, if someone has any MIDI sequencer library suggestions, they are 
welcomed.

Have a nice week-end,
