With Zone 1 selected, go to Edit - Stage Setting - Common Edit
Go to Pedal 1 - Mode and set it to Momentary.
Go to Target Edit - set Target to CC11: express. Set the Min Value to 127 and the Max Value to 0. This should allow the zero expression value to be sent while the pedal is depressed and 127 when released.
Go back to Stage Setting - Zone Edit - Controller Edit and make sure Pedal1 Enable is on only for Z1 and off for the rest of the zones.
If the on and off are too abrupt, you can lower the value of the On Rate and Off Rate in the Stage Setting - Common Edit - Pedal 1 menu.
