I grabbed this from sequencer.de and sorry about the small size, but it’s all that seems to be out there! But what we can plainly see here are a rows of knobs and what looks like a row of step buttons.

So now we know that the Aira line includes at least an 808, a keyboard of some sort and now this seemingly groove-like device. We can also assume, based on logic and some babble in the videos that we can expect a 909 as well.
