Keystroke Error when trying to use media control (OSX)

I am trying to send keystrokes on Mac to control Youtube Music Player
1 tap for play pause, 2 taps for rewind, 3 taps for skip
Youtube Music responds to my keyboards play/pause, FF, and rewind button, as well as the built in OSX software keyboards shortcuts.

I tried to send these predefined keystrokes in Midi Translator Pro, and it gives me the following error:

If I change the keystrokes to something else, like the letters “A”,“B”,“C” it works fine.
I’ve tried a few other keystrokes like tab, left arrow, etc and they work.
However other functions like “browser back”, “home”, do not work.
I can test other of the special keys if you want.

Hi and welcome to the Bome community!

  • Could you please share the project file you are using?
  • What keyboard are you using on your Mac?
  • Is Youtube Player on Mac a native Mac application of something downloaded from the Chrome Store or perhaps a WIndows App used under the MacOS.
  • What version of MacOS are you using? (I don’t think they call it OSX any more)

I have a MacBook Pro, I should be able to test with but my keyboard doesn’t have any Media Keys so I might need to get creative with an alternate keyboard to do any testing.
