Hi Rene,
To make CC notes visible, you can use MidiOx (for Windows) or Midi Monitor (for MacOS).
When you press a button on the BCF, data will show up in the software. You need to put the CC note (Data1) in the index part of the midimap.
Eventually, it works like this:
BCF Press button --- CC note + Data --> Midimap --- Action --> Cuelux
