Try looking for "Abstraction 6" (that's the title).
And thanks for the compliment.

The idea is that it's structurally in 12-tet, but locally, chords are bent to be in JI. the sax is always in 12-tet, the other notes in the "tape" part "crystallize" in JI around it.

It's not really "adaptive", because that implies that nothing is ever exactly in ET or JI; in this case chords ARE justly tuned, exactly, and the sax IS in 12-tet, exactly, but, the relationship of a chord in msr 1, to a chord in msr. 21, is probably not rational.

No, it is adaptive JI. There, the chords are JI but the
melodies are not. Adaptive temperament is where both chords
and melody are tempered [though not all authors support this
distinction, "adaptive JI" always includes what you're doing
here]. To make matters confusing, Bill Sethares uses the
term "adaptive tuning" for the thing where timbre and tuning
are matched.
