MIDI input transform question

I’d like to map my foot controller CC11 messages to their inverse: 00 becomes 127, 01 becomes 126, etc. The formula would be 127-Value2, but I am at a loss as to how to program this into the MIDI transformer. Anyone have experience with this?

Upper section…
Type is___Equal___Controller___and
Value 1 (MIDI Controller No.)___Equal___11

Lower section…
Value 2___Mirror___64

Function = “Transform”.

Don’t forget to “switch on” the module :wink:.
