Re: [fluid-dev] Manipulating the 16,384 values of pitch bend

[Ben Gonzales]

Hi Dave.

The pitch bend controller simply moves between the upper and lower 
limits. The pitch bend RANGE is what you need to set. I don't know what 
the default is for FS, but from what you said it sounds like it is 4 
semitones

Google "pitch bend range" and you'll get the required MIDI commands
