This command is equivalent to receive MIDI 'pitch bend sensitivity range'
message which is a RPN MIDI channel message:
pitch_bend_range channel_number semitone_range
In your exemple: 0 is the channel number (0 based), 12 is the range.
This MIDI message is received only by MIDI channel 0.

The spec defines a default modulator for this purpose (SF2.01 page 57 section
8.4.10 MIDI Pitch Wheel to Initial Pitch ....).There are 2 solutions
1) One can add a new modulator at instrument level (global or local) to be
able to supersede the default modulator.
For exemple an amount value of 25400 (in cents) will produce +4/-4 semitones
range.
This solution impacts any note played on any MIDI channel.
2.1) One can send a MIDI RPN pitch wheel sensitivity message on the concerned
channel. (see MIDI spec to know RNP number).
2.2) The above command can be put in a config-file. Then invoke fluidsynth
application with option -f config-file.
