The range for pitch bend is (numerically) -8192 to 8191.
The unofficial default for MIDI is for this to be -2 semitones to +2 semitones. This value can often be changed by special control messages (can't be done in NWC, but can be added later by a MIDI sequencer program).
I think you'll find that -1 semitone is -4096 and +1 semitone is +4095. I'm not sure that the correspondence is guaranteed to be linear, but I think Fred found out that it was anyway.
