Re:VRML - Octony and double tie circular mirroring

Here is the 7-limit octony, with some of the chords:

In that one, utonal = red, otonal = dark blue.

It looks nice, but it's not the best way to demonstrate this scale, in my
opinion.
The "feature" of this scale are its eight tetrads 4:5:6:7 and 1/(4:5:6:7),
and also
its circularity. I haven't thought what the best way is for a 3D model,
that's a
puzzle you're much better at. Your model has 6 squares, so maybe something
with 8
squares. Then when you click on a square, a tetrad would sound. Also, each
tetrad
has 2 tones in common with an adjacent one, which is why it's called
double-tied.
Maybe you need more dimensions, I don't know.

Okay, thanks, solution is to add the 1 at the centre to make the 8 triads into 8 tetrads, each sharing an edge:

What a remarkable scale!

N.B. midi clips are all ascending broken chords on orchestral harp. To remake them in this fashion, you need new command
#asb, which will be effective in next upload of FTS beta. (Prev. upload always plays notes in order in which they are
defined in the file name).
