There's sort of two ways to look at the Teenage Engineering products. The first is as a tool to produce music, and the second is as a kind of interactive sculpture. The design and production of these things is so good they are almost like art themselves. Are they useful? Not really, you could achieve the same thing with a VST — hardware isn't required for this — but to think in this way is to miss the point.

Are sculptures, picture frames, decorative vases and ornamental unused candles unnecessary?
