I\'m using GS with Sonar 2XL. Before using GS, I used to just use Soundfonts in Sonar. I have several files from those days where I used the pitch bend on my keyboard. Now in GS, those pitch bends are not sounding (I\'m just hearing the initial note without the bend). Everything else sounds OK, except that.
You just need to assign a pitch bend range in the editor. Double click on an instrument in the Editor and the Instrument Properties window will come up. There you will see a place to assign pitch bend range from 0-12 in semitones.
That should do it
