Building a USB MIDI 2.0 Device

Good to see the platforms (MacOS X, Linux, Android) building support, but there is still not a single MIDI 2.0 controller on the market (that includes the somewhat flawed Roland A-88Mk2 which maybe, maybe is hiding 16-bit velocity and 32-bit parameter support inside it's current, MIDI 1.0, not-even-aftertouch casing).
