Audio track ghost CC or Vol changes

Since updating to Cubase LE 12.0.50
Some audio tracks are resetting their own volume.
It’s intermittent
Also, there is constant midi out activity even when nothing is playing
I also updated drivers for UR22 mk2
Any known bugs?
Launchkey 37
Steinberg UR22mk2
Cubase 12.0.50


My guess is, your MIDI device behaves as a Remote Controller and sends some unwanted data.

any idea how to check this?


Open Studio > Studio Setup and have a look, of there is any Remote Device available. Then double-check the Input MIDI Ports of the Devices or attach a screenshot(s), please.
