I have set up a preset that applies denoise at 50%. If I click on the preset in the left preset panel in lightroom it applies denoise to the selected photos.
If I press the button on my Behringer

x-touch that is assigned to the preset it applies the preset, but doesn't do the calculation and I need to click on the update button under the histogram where the masking, adjustments, spot removal, and crop tools are.
I'm running the latest version of lightroom classic (14.4), MIDI2LR 6.2.1.0 and windows 11.
I think this may be a bug with midi2lr
