Problems with midi routing in Sonar Platinum

Hi,
 
This has onlyjust started happening.....
 
Running Platinum, latest version. Using VSTs Kontakt, AD2, Omnisphere 2. Using Novation Launckey mini controller.
 
Using my VSTs by dragging them into the track view, as instrument tracks. Got about 8 of them running, each a different variant of a NKI. Record all fine, got the track running nicely. I go back to it, plug my controller in and all of a sudden the midi in each track is routing to the VST in the track above it. So, say track 3 is a drone in Omnispher, and track 2 is a beat in AD2. The midi in track three is triggering the AD2 VST. This continues through the whole project and only happened when i plufgged the controller in.
 
When I started the project, same controller, all worked fine. Nothing has changed.
 can't fixi it!
