One of the biggest surprises of NAMM came from a little booth at the end of the show! CME have a new USB keyboard coming out that sports polyphonic aftertouch and full-size keys in a tiny form factor!
Not only does it support iOS (via USB), their demo features Arctic Keys! Arctic Keys, along with other apps like Animoog and Grain Science, can make use of polyphonic aftertouch to modulate parameters. Think about it as a hardware version of playing Animoog's keyboard, where moving up and down on the keys themselves is a modulation source for that individual note. Poly AT is fairly rare in keyboards, and is usually prohibitively expensive. Even my beloved MPK61 only does mono aftertouch.
