No, you aren’t missing anything. This is so rarely used that there is no “one-click” solution for this. Btw. what do you intend to do?
One way is to use a math expression. A very easy one – insert the following into the “Expression to evaluate when calculating the midi message value from the modulator value”:
127-modulatorValue
That is if your modulator goes from 0 to 127. The modulator will still show values from 0 to 127 but it will send values from 127 to 0. If you want a modulator that shows the correct values you could usa a uiFixedSlider. You will find some examples of fixed sliders if you search the forum.
