Thats somewhat semitone biased, if we use +1.0 is middle C, +2.0 is one
octave higher then we are tuning neutral, and, coincidentally compatible
with 1.0volt/octave analogue synths.

Well, no, because for advanced instruments (eg. a full featured sampler)
we have jack.

I think its reasonable to expect a jack app to be able to natively
understand MIDI/OSC/CV/whatever.
