Certain VST Tracks won't play in Cubase

Hello, I’ve been configuring a lot of different MIDI control surfaces and things like Divisimate into my template lately, and all of a sudden, certain VST’s won’t play with all MIDI inputs selected. I have a novation launchkey, and I’ve always had my instrument tracks set to all MIDI inputs, and everything was fine. Now, Kontakt or Sine might sound initially, but then if I close the VST and pull it back up again, it doesn’t have a sound at all. Synth plugins like Pigments sound without me playing, and then play that sound forever. Some wacky things are going on, and I cannot make music. Any help would be appreciated!

PS, I know this is a Cubase problem, because the same MIDI inputs and outputs are set in Ableton, and it works fine.

Solved - I just turned off “all midi ins” on my control surfaces.
