newbie question - tuning

[ido]

Hi

just bought the RME version. great synth

then i noticed a problem concerning the tune. it seem that all 3 oscillators are not in tune. (need to be adjusted around +2 semitones)

i can adjust in the MASTER-->Transpose In/Out-->Midi Key transpose = +2.
but in my mind it must be the wrong way.

Is there a way to callibrate ?

Thanx.

[till]

Fine Tune knob (on the left hand side) on fully left position versus the 12 o'Clock zero position?
