Mac has four mod keys available in Cubase, and Windows only has three because of the Win key being used by Windows. Pro Tools lets you use the Win key just as you would the fourth mod key on a Mac, so we know it can be done very reliably. It would open up a huge amount of extra custom key commands in Cubase, which Mac users have enjoyed since the beginning. Once you’ve been on Mac you see what a big advantage it is if you like working fast with lots of extra key commands.
Options could be:
Make it completely optional for people who for whatever reason don’t want it.
Make it so that the Windows System hotkeys stay as they are, and the rest are available as desired for tons more Cubase custom key command joy.
Win/win for every single person.
