MIDI Monitor to determine specific devices

Hi folks. I’m getting a bunch of seemingly random MIDI CC messages showing up in my tracks in Cubase 12. I’ve powered down all my MIDI gear, closed my iOS apps (Metagrid Pro & Patchboard), and yet they’re still showing up in MIDI Monitor. Is there a way to determine which MIDI device they’re coming from?

Thanks.

Create a MIDI track,
go to its Inspector.
Change the MIDI Input, check out all of them one after another.

…well jeez, now it seems obvious.

Thanks for the suggestion, I did that and it turned out to be Keyboard Maestro, I’ve excluded that from the All MIDI Inputs, and so far so good.

This is my new favorite little tool for MIDI trouble shooting. Shows you everything you need, including the source device that sent the MIDI Message.
