How To Change Pitch Bend Range Value?

Hello,

When using pitch bend through the Intrument Midi Control for VSTi, the pitch is modulated on +/-1 octave. I’d like to restrain it to +/- one tone. I know it’s Hydra’s purpose, but pitch bend message cannot be mapped currently, so I don’t think it would work this way. Is it possible anyway?

Pitchbend range generally depends on settings of the Instrument (VST, external MIDI etc), not on the controlling device.

OK,

So far, I wanted to avoid to be specific about VSTi I’m using but I guess I’ve no choice. ;)

Is there always a parameter from VSTi associated with pitch bend? I’m using a VSTi (Unkown64 Pro) that has no GUI pitch bend parameter .
(Or if someone use this VSTi and know where the parameter is, any help would be appreciated. ;) )
