That documentation that says the note will send a value of 127 when released doesn’t make sense to me. The ‘Global Midi Monitor’ is accessed via the ‘Window’ menu bar item. You could do a recording of a single press/release of the note button, and then a single press/release of the cc button.
Also, it’s usually best for the widget to only learn the note ‘on’ message, not the ‘off’ message. This might need you to manually edit it, or deslect the Learn button before you release the controller’s button.
