I would like to specify that the pitch-bender wheel should transpose the sample by 3 semitones, not the default 2... but I can't find any reference on how to do this.
So far I successfully set up a labeled-knob binded to GLOBAL_TUNING with minValue="-3" and maxValue="3" and it works ok.
But it's only controllable with mouse on the UI.
If I use the pitch bend wheel it still has the range of -2 / +2 semitones
