Actually, that piece is written for simple regular 12-tet guitar. The
Tape adds the 7-, 11-, and 13-limit intervals.

No, I understood that. What I meant is that not every note from 12-
equal can be harmonized in every possible 13-limit way. For instance
only 5 or 6 notes can have a 16/13 neutral third, likewise only a
certain number can get 11/6 neutral sevenths...for each type of 11 or
13-limit interval, there are only certain notes from 12-equal that
can be used since there are only 5 11- and 13-limit frets. So if
your piece used, say, a G# with an 11/9 neutral third, you couldn't
play it on the Ultra Plus. If it was an A with an 11/9 though, then
you'd be fine.

If you'd like, you can even post the chords used in your piece and I
can tell you which ones would be playable and which wouldn't.
