YouTuber KlaatuNinja got a preview build of Amplify's KRFT. The app looks very similar to their NOIZ app, but this one is being designed for musicians who want to play their own music. According to a post on the Audiobus Forums:
"You start with a blank Surface and add your own elements to create up your jammable track or instrument. There's no social, login etc; it's purely for music making."
Or as Klaatu puts it, "This is what they were talking about in the first place and it's like lemur with synths and samplers built in. With the keyboards as well as piano roll and pads for the drums it's getting there."
