However, it (MIDI) also has its own age. And
limitations. In particular,
the
amount of per-note control is pitiful.

They did, "Key Based Instrument Controllers" provide for per-note
controllers.
Granted MIDI remains stupid. MIDI is 15 different ways of saying "set this
control".
All of MIDI can be reduced to two messages: set-control (addressed by
Channel, Voice and Controller ID) .. and SYSEX - for data-dumps.

Just make the events
pure, raw MIDI. Jack MIDI events are 'just n bytes of MIDI', Alsa has
functions to get at 'just n bytes of MIDI', and... well, it's just MIDI.
However, it also has its own age. And limitations. In particular, the
amount of per-note control is pitiful.
I can always use hacks to get around the limitations, or introduce a
per-note control via separate "set note parameter" event type. But hacks
are ... hacky, and the extended extension of extension for every single
feature is a bit inelegant too.
Anyway - so far, I have no code that would make use of this, so we might
keep it as plain MIDI. And then we have next 5 years to decide the
details of the feature. In the meantime, maybe the MIDI guys will decide
for us :D
