Does anyone know of any Android applications that can enable use of tablets with Cubase on Win7?
Not right off but one could be easy to build and will eventually appear. I’d spend less time looking for something tailored to Cubase, and start looking for one that does MIDI controller information. This could be hooked up via WiFi and some LAN-Midi software that creates virtual ports in Cubase.
At that point it would work just like any other physical controller.
