Here's a table of the *range* of the virtual pitch continuum
which can be represented by each 144-EDO note. I cover only
one semitone, as it can be reproduced similarly for the other 11.

The table gives the absolute Semitone ranges (i.e., cents
as a fraction of semitones), the nearest 12-EDO degree and
its cents deviation (i.e., to relate 144-EDO to Johnny
Reinhard's 1200-EDO notation), and MIDI pitch-bend values
for the deviation from 12-EDO.

This emphasizes the use of 144-EDO as a *notation*, rather
than as an actual tuning. (The latter would give the precise
cent or pitch-bend value of each 144-EDO degree, which I've
done here before.)

This is how Dan Stearns and I use 144-EDO to *represent* pitches
which we expect to actually be tuned slightly differently,
usually JI in my case, and poly-EDOs in Dan's case.

(This post is a preliminary to an upcoming one about
my _Spider_ piece.)

Rats! I forgot to put a subject line. Please use this
one if responding to this post.
