Leave PitchFactor in Bank Mode. Assign the Aux Switch so you have:
Aux1 (Tip): Bank Down
Aux2 (Ring): Flex/Learn
Aux3 (T+R): Tap
Now you can cue up banks in either direction and press PitchFactor's Left of Middle Footswitch to select a new preset.
Thanks for the reply Alan, seems i rushed through my setup, again!! I will give your suggestion a go.
