Software wise, they’d have to rewrite the extension for Cubase.
Firmware wise, they’d have to re-spec the unit, removing browser functionality.
Business wise, it may not be a good investment of time and money to do either. There are other CMC units better suited to the role of channel control. The AI is not one of them.
As I stated before, the AI controller is mostly for plugin control, not channel control.
It doesn’t make sense to have channel switching functionality on a controller that you’re going to reach for when you want to change something like resonance in a plugin.
If you want channel switching functionality, why not program one of the user assignable keys to it?
Don’t forget that a German made that happen.
