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.
