 The problem is
 they have no effect on the synth. I've been using Calf Fluidsynth, but
 tried the standard
 Fluidsynth and Yoshimi, but with no joy. I have tried patching in midi
 commands to set the
 pitch bend range to 12 (RPN 0,0, DATA 0,12) and tried the pitch_bend
 command in the
 standard Fluidsynth but nothing doing not even a semitone shift. 
You might have a try with Pure Data, where - for example - scaling the
range would be quite trivial (although of course you would still be
losing in 'resolution'). Also you could use it for quickly prototyping
midi message 'manipulator' patches, for example a while ago I hacked a
patch to use a Vestax PAD-One controller (which sends note-on messages)
to send bank and programme changes to yoshimi... and that was done quite
easily in Pd ;)
My two cents.
