This doesn’t smell as being a legit leak. Just look at the quality of the image, is this anything like what might come from a product development team. It isn’t even in the category of believable to me. Plus read all the qualifiers ask.audio puts around this, they don’t believe it’s legit either.
Ableton is certainly capable of doing a standalone controller, and they might well have a prototype in the works. It almost certainly has been discussed in a design meeting there. But Ableton is also a lot more capable of doing a leak — and this ain’t it.
ADDED: Ableton has given official notice — THIS IS A FAKE !
Big demerits to ask.audio, for giving this the light of day, when they knew it was false, and to the wanna be cozy-bear whoever that is, for constructing this disinformation in the first place.
