Midi Controller / Version Lightroom 3.4.

Hello dear forum 🙂

I have the Lightroom version 3.4, basically the subscription. I wanted to connect a midi controller (X Touch Mini) and downloaded the Midi 2LR program. Unfortunately, Lightroom does not recognize the program. Can you help me?

- Is the Midi 2LR compatible with the Lightroom version at all?
- Are there other programs?
Or did I buy the wrong midi controller? Which would be compatible?
Sorry don't know my way
LG Sven
