This is simple math, but worth sharing because of its usefulness. If you ever have to have a controller behave in the opposite way of how it does by default, you can achieve this with a very simple equation:
On the rules-tab of the translator in question create an “expression” rule. Using “pp” as the value-variable in the translator, the rule reads:
pp=127-pp
This was useful to me in order to, for example, have the same knob open one send-signal in Live while closing another.
