MIDI 2.0 implementation

[sm-Fifteen]

Over the past year, the MMA has been detailling the various components of the MIDI 2.0 specification and working to define things such as an official MIDI 2.0 USB profile. The MIDI 2.0 protocol itself aims to extend the MIDI 1.0 protocol in a back-compatible way (such as by introducing higher resolution note-on and data/control change messages), as well as formalize the use of profiles (which is what GM2 essentially was, but also things like MIDI Show Control and the like), feature negotiation and making controllers into more of a configurable set of features than a list of spec-reccomanded/profile-mandated CC numbers.

It could be interesting to look into adding support for this new extended protocol here.
