AXiS-49 improvisation in 22-tet

Since MMM seems to be dead these days, I'm going to take a cue from
Chris V. and post music here as well.

I recorded an improvisation on my AXiS-49. The whole thing was pretty
long so I edited 4 smaller parts from it. The playlist is here:

Afterward, I went back and embellished on the 11-equal progression a
bit, harmonized it, worked out a melody for it

Here we can see me mangle an explanation of the porcupine comma pump on camera:

It is apparently true that if you're ever on camera at 5:30 in the
morning and need to discuss regular mapping, the first phrase that
will come to your mind to describe motion downward by 10/9 is "go down
by a small thing." Anyway, since I said I'd have to discuss it in the
email, the chord progression is (in meantone)

Cm7 -> Ebmaj7 -> Ebm7 -> Dbmaj/Eb -> Dbm7 -> Cb/Db -> Cbm7

except in porcupine, instead of ending up at Cbm7, you end up back at
Cm7 again in porcupine.

Hope you enjoy.
