When plugging *XY Pad to a vst/audiounit, should the interface autoupdate when moving XY?

hi, i’ve plugged the *XY Pad to a vst/audiounit.
I’ve correctly set up the X and Y to control a parameter of the plugin each.
when i have the plugin interface open, and click around in the xy pad interface in trackdsps
should i expect the visual parameters of the plugin (in this case, OhmForce OhmBoyz) to visually update?
i.e. should i expect that knobs would move in the interface, etc?
