Well, we could go back to Sonic Foundry Acid, pre-Ableton, and even further as necessary .. what I refer to though, is the iOS User Experience, which is shockingly similar for an app built a year or two after Endlesss had already established primacy as a clip-based collaborative music-making app.

Great link though, thanks for sharing that! Very definitely a deep rabbit hole for music technology boffins to inspect ..
