MIDI2LR  3.3.0.1
MIDI2LR is an application that interfaces MIDI controllers with Lightroom 6+/CC Classic. It processes MIDI input into develop parameter updates and photo actions, and sends MIDI output when parameters are changed for motorized feedback (on controllers that have motorized faders). A listing of available LightRoom commands is in the Wiki. Assistance on the code and design is welcome.
