FCB1010 expression pedal not working after using stomp box (Pure Booster)

  • Hi all!
    I'm using a FCB1010 with the latest Uno Chip, upper row defined as Stomp boxes.
    (KPA is running 1.1.1, but I had the same issue with version 1.1.0)


    Volume pedal is working fine as long as I'm not hitting the stomp X - "Pure Booster".
    If so, then I'm left without a working volume pedal until I switch to another rig and then back again.


    Any idea what causes this?
    Or, even better - how to cure the problem?


    Regards
