The only way I've found to reliably fix this is to: The odd thing is, this only happens after (1) a certain amount of time or (2) I do something specific (I can't seem to figure out what triggers it). Also, the wheel stops working (won't switch between tracks or between clips, and the transport controls stop acting like transport controls and just send MIDI note signals. When I switch to XO on track one, it still displays the info (screens and light guides) for track 2. The S49 shows the Strummed Acoustic info (screens and light guides). For example, I currently have XO on MIDI track 1 and Strummed Acoustic on MIDI track 2. When I switch through them in Live, while the sound will change, the screens and light guides on the S49 will remain stuck on the same track. I can't figure out what causes it, but the S49 screens and keyboard light guides will get 'stuck' on a specific patch.

What I really like using it for is to browse Komplete Kontrol on the keyboard and change patches, settings, etc. I recently added a NI Komplete Kontrol S49 MK2 to my setup (complete setup notes at the end), and while I love it, the behavior is a bit weird. Hey all, really could use some advice here.
