I agree that HALion and Falcon's UI's are also overly busy and as you say, information-dense. But they are not nearly as convoluted as Kontakt's. Sure, with enough time any horrible UI becomes familiar and perhaps even understandable. But Kontakt is a particular challenge in this regard. It's what happens when the lunatics run the asylum, i.e., when engineers start making UI decisions that they are not qualified to make.
IMO, all the best technology companies are led by what are essentially former Product Managers, everyone from Apple on down to Spectrasonics. It's telling that Apple isn't as innovative as it once was now that an Operations guy (Tim Cook) is running the show.
But back to the topic at hand. Super 8 has an excellent, easily understandable UI that is deceptively powerful. That's what companies should strive for, IMO.
