Please note that ReaLearn 2 should be out within a week. It has many new features, including a replacement for the LBX SmartKnobs workaround ("Auto-load preset"). If you want, you can check out today's prerelease v1.12.0-pre21.
@cjewellstudios Would be a good time to make an updated version of the YouTube tutorial, in case you are in the mood
