I'm having problems with Stream Deck and Vectorworks as well, for some reason Vectorworks is not recieving hot keys.
I have the same problem when I try with a X-Keys device.
When I have a hotkey that consist of two keys like <Alt>+<0> vectorworks will only react to <Alt> and not see <0>.
Both devices work when I try them in notepad and with other programs.
Have anyone else had this problem?
I'm running Vectorworks on Windows 10.
