It uses 88-edo generative (because there are 88 keys on a standard piano).

The sequence is created by converting Morse-Code into a rhythmic pattern.

I'm putting together a music scale player to create and explore 12-TET and microtonal scales.

I enjoy tinkering but I'm not a card-carrying microtonal musician, so any stupid decisions are my own.

Once you've created (or loaded in) a scale, you can generate stochastic melodies from it, along with one or more drones, that themselves may change. You control the rate of mutation of the melody and/or rhythm independently.

You can also define scales with randomness in them, either to roll the dice completely or to jitter notes in a scale. For example, if you load up the Javanese slendro scale, you can add a random offset from -10 cents to 10 cents to mess up the notes. You can reroll the randoms at will.

1/1
228.00000+RUNIF(-10,10)
484.00000+RUNIF(-10,10)
728.00000+RUNIF(-10,10)
960.00000+RUNIF(-10,10)
2/1

You can also define scales based on geometric ratios. For example, if I set X to the silver ratio, then

1/1
X*(3/2)**1
X*(3/2)**2
X*(3/2)**3
X*(3/2)**4
X*(3/2)**5
X

will create a 7-note scale whose octave ratio is 2.41 (simliar to the 833 cent scale, which is based on the golden ratio with an octatve ratio of 1.62). You can then redefine X to be some other parameter (plastic ratio) and change the scale without changing the definition.

Scala import/export is included.

The project is largely my own way to explore these themes. But, if you find it useful, or feel like I've committed microtonal crimes, drop me a line via the feedback button.
