I am having the exact same problem with PITCH on my MOD 11 which I bought on Ebay in November but only started using just now. I live in Hong Kong where the voltage supply is 220 volts and added it to my board using a Boss daisy chain. All patches on the MOD 11 work fine EXCEPT Pitch.

I have tried the adapter that came with the pedal but as it’s designed for 120 volts (USA), it does not work at all.

Any thoughts, please? My primary reason to get the pedal was for the Arpeggiator mode in PITCH..!!
