The Lumatone is a keyboard made up of 280 colorful, shape-isomorphic keys. And the best part?
The tuning is fully customizable.
The key colors are similarly customizable, so the picture shown is my own take on a 31edo layout. It's what's called a Bosanquet-Wilson layout, with chord shapes being the same regardless of the root note, and simple chords all decently accessible. Important scale patterns are shown here. I split the notes up based on their roles in the keys of CGDAE, which generally carry over well into other common keys.
| Scale | Keys |
|---|---|
| Major | F, C, G |
| Minor | D, A, E |
| Melodic Minor | G |
| Neapolitan Major | G, A |
| Harrison Major | G |
| Rast | G |
| Bayati | A, E |
| Neutral Lydian | C, G |
| YB Altered | Gb |
| Mode 8 | C |
| Dylathian | C, Gt |
| Whole Tone | C, Bb, Ab, Gb |
The coloring of the keys is a version of Kite Giedraitis' Color notation, with white being for C, G, D, A, and E, yellow being for B, F#, C#, and G#, green being for F, Bb, Eb, and Ab, blue being for D#/Edb, A#/Bdb, E#/Fd, and B#/Cd, red being for Db/C#t, Gb/F#t, Cb/Bt, and Fb/Et, light/grayish blue being for Gd, Dd, Ad, and Ed, grayish red/pink being for At, Dt, Gt, and Ct, and gray being for Bd and Ft.
Using this coloring system, the "standard key" for a scale is that which uses all or as many white keys as possible, with examples shown. These are good for orienting yourself while playing.
Here's a link to the keyboard shown, an alternate coloring, and an alternate layout with seven white keys.
