Representing notes #8

There are at least three different useful ways to refer to a note: Midi number: 60 "musical" note: C4 (middle c) frequency : 261.63 hz all the info

We can just have a data structure with all of this in it. Just a vector of maps, I think; and then we could have index-by fns if you want to reference one of the vals

At any given time, we might want to work with the note as any of the three attributes. This is why I like having it as a map. But if we want to do a simple operation like dec by 2 semitones, we now need special function specifically for this new data structure. Is this ok? I think so.

Using a map everywhere is getting ugly fast. Perhaps it's best to always use midi, and look up the freq / note name when whenever we need it
