This may be an old topic but I can't seem to find a "tuner" button/function in Gearbox when using POD X3. It has the "tuner" button/feature in GuitarPort but not with POD X3. I would assume Gearbox would have the same feature for the POD X3 since its a better interface and I know the POD X3 has a "tuner" button on the actual interface. Maybe an update with that feature in the near future???? Any information about it would be helpful.
