the modern western mode of 12 Tones Equal Temperament (12-TET) is the default and likely the one you are most familiar with. once comfortable with the ui, i recommend exploring other N-TET versions to see what what harmonies your intuition guides you towards!

to better help you understand these N-TET modes, there is a 2D geometric visualizer that will computes the geometric shape of your chord and match it against common chord classes (major, minor, 7ths, 9ths, etc.)

the 2D version uses a realtime 2D convex hull algo.

there is also a 3D Tower version that hacks around the 3D convex hull algo (looks accurate but not accurate)

there is also some basic synth sound design implemented as well.

please enjoy!

It worked one of two ways, I'm not positive which.

--------

You stared with musical note C. One note could be played at a time. G would go down a half note, H up a half note. F down a whole note, J up a whole note. Repeatedly pressing G would go down the chromatic scale. Playing a Diatonic scale up would be a combination of pressing H and J.

--------

Pretend the keyboard letter G is the base note, mapped to C in music. F would give a half note lower, H a half note higher, and so on across the home row of the keyboard. Then you could adjust the base note (perhaps T to go down a half note, Y to go up a half note).

In essence, you could transpose a song from the key of C to D by doing a modifier, and your fingers could complete the exact same sequence. In a jazz application, something on Spiral Synth like "FSA, GDS, HFD, K" might have been

On desktop it's awesome. Very cool!

Also, I really liked your audio performance monitor to debug the audio engine. I've done a lot of work with Web Audio and it's so annoying to "visualize" or "track" what's happening.

I've been searching for a decent "F12" / "Developer Tools" for it.

Why doesn't clicking on the key spiral trigger the same visualization in the right panel that using the keyboard does?

I wonder if "shift" would be a good modifier to some of the key behavior (reverb?)

And no-one remembered Loom..
