I can’t replicate this as of yet, but at some point custom keyboard shortcuts I’ve made simply stop working. They are still listed under “key commands”, and deleting them and reassigning them doesn’t work. Loading a complete other command set and then re-loading my custom one also doesn’t fix it. Closing and re-opening a project does not fix it. If I restart Cubase then all is well again. Other shortcuts remain functional.
I am on Mac, so if you’re certain the virtual keyboard in the Transport is off all I can offer is the suggestion to start Cubase in Safe Mode and see if your shortcuts work.
You might try loading a different Key Commands preset to see if that works to aid in your troubleshooting.
Sometimes I key the VK key combination by mistake but the VK is
off the screen (or buried behind a window)
so I don’t realize that it has been activated yet.
So I’ll spend the next minutes punching uselessly at the keyboard till I remember:
Ah yes, it probability that VK thang again; and sure enough more times
than not, that’s the prob.
