Many keyboards support varying pressure on a key to vary the sound, this is a common input. This is true only of velocity and monophonic aftertouch. Polyphonic aftertouch is actually pretty rare. The only controllers I know which provide it today are the Native Instruments Maschine series. The only synth engines I know which support it are Serum and Animoog. But it died out not just because of "buzzkill accountants" or whatever the article said, but also because very few people wanted it. And the idea that it's the secret sauce in Vangelis's Blade Runner soundtrack is just dipshit ridiculous. This article is typical of Wired-- Junk technology writing. They haven't really been competent since the 1990s. I can't totally agree. They've definitely gone downhill, but this was probably the stupidest thing I've ever read from Wired, so I can't call it typical.
