I don’t think that this would be enough for most people. Apple has raised the bar a lot with the latest remote app for Logic and they even give it away for free. The app is of course only available for iOS because it’s an Apple product.
But Cubase is dual platform and it’s fatal to ignore Android on the long run because it is Android, what people really use outside the minuscule but verbose Apple universe.
Currently Android is heading towards a market share of 80% on the smartphone market and 70% on the tablet market and the numbers grow fast day by day. And the OS not restricted to phones or tablets. Android works fine on many TVs, fridges, printers, watches etc. from many different vendors.
It would be great to use a cheap TV as a giant meterbridge for the mixer or just tap on the wrist to remote control Cubase. The ideas are endless and this is not something for a distant future, it could be real already now.
But for this we need a remote app first.
The main problem I see for the app is a possible veto from Steinberg’s hardware department. A cheap Android tablet with iC pro would be a lot less than their current hardware controllers and it would offer a lot more functionality (wireless, switchable views etc). And selling hardware is a good source of income while a software product may not be as secure.
