CuPro 10- MIDI controller moving faders?

My MIDI keyboard/controller is causing faders and pan knobs of various tracks to move.
It has never done this until yesterday, but now is doing it with 2 different controllers (Nord Stage 3 and a Roland A300 Pro), both with USB connection and MIDI cable connection.
Which MIDI settings would I need to check to get rid of this problem?


ASUS ROG laptop
Cubase Pro 10
Roland A300 Pro controller
Windows 8.1 64bit


Double-check Studio > Studio Setup. Make sure there is no Remote Device. If there is any, make sure, there is no MIDI Input port set (even not All MIDI Inputs). Set it to Not Connected, please.

That seems to have done the trick. Thank you for the suggestion!
