What can you do with a 5x7 grid?

Hi all,

I just downloaded the "Sound Squares" app for iPhone, which lets you
set up a customizable 5x7 grid and tune it to anything you want.

So it seemed like the best thing to do was to go for 15-TET, since you
get two octaves and a major third. I set it up with the 240 cent
interval going along the 5-length axis and the 160 cent interval going
across the 7-length axis. This means that you get porcupine in one
direction and Blackwood in the other direction, which seemed sensible
to me.

Can anyone come up with any other brilliant ways to set this up? Maybe
there's a clever solution for 22-equal that I'm missing. It would be
much appreciated.

-Mike

I'm making a preset for

x 4 5 6 7 8 9 10
6
5
4
3
2

and possibly one for

x 6 7 8 9 10 11 12
6
5
4
3
2

for starters. -Carl

I don't know about brilliant, but at least it's in a tuning that doesn't suck rocks through a hose: an octave of 31et with five horizontal diatonic scales.

Thanks for the responses from both of you. I'll check them both out.
In the meantime, I recommend that folks check out the porcupine setup
I have going - just make the short axis be the large step, and the
large axis be the small step. This way, porcupine[7] is one step up
and then 7 more to the right.

If you do this in 15-tet, then two columns along the short axis gives
you blackwood, which is an extra perk. But you should do it in 22-tet
to be safe though.
