Ok again, just incase I was not understood.  Suppose, I just bought the H9, added the Pitchfactor Diatonic algorithm, with NO AUX PEDAL.  How do I use the Learn/Plex pedal/function to select the key I am playing in?

Please don't take the caps above as me yelling, I just wanted to make sure to imphasize that no external Aux pedals are attached.  The unit is theoratically out of the box with the added Diatonic Algorithm.

Thanks,

Tommy
