To use my profiles there are a few things to be done:
1) Reset the X-Touch to default using the X-Touch Editor and the LayerA.bin and LayerB.bin files attached to this message. (just in case you need these)
2) Drop the xml files in the profile directory (most likely the plugin directory)
3) Start LR and change the MIDI2LR options settings according to the screenshots.
This should be enough in most cases, please be aware that I have a few special modifications (because I am using a German keyboard while LR is set to English) that may have to be changed.
