Simple Modular Scale

Modular scale based on an array of ratios

Usage

``bash
npm i simple-modular-scale
`

`js
var ms = require('simple-modular-scale')

var scale = ms({
base: 16,
ratios: [3/2, 4/3],
length: 8
})
// [ 16, 24, 32, 48, 64, 96, 128, 192 ]
`

Options

- base is the root number from which all values in the scale are derived
- ratios is an array of numbers that are multiplied by the previous number in the sequence. Ratios are alternated to create a sort of multi-stranded modular scale.
- length is the total number of values output.

Example

`js
var ms = require('simple-modular-scale', {
base: 16,
ratios: [ 9/8, 4/3, 4/3 ],
length: 8
})
`

Multiplicand | Multiplier | Product
-------------|------------|--------
16 | 1 | 16
16 | 9/8 | 18
18 | 4/3 | 24
24 | 4/3 | 32
32 | 9/8 | 36
36 | 4/3 | 48
48 | 4/3 | 64
64 | 9/8 | 72

Starting with a base of 16, the next number added is 16 * 9/8, which is 18.
Next 18 is multiplied by ratios[1] or 4/3 to produce 24.
Then 24 is multiplied by ratios[2] or 4/3 to produce 32.
This sequence continues until an array of length` is produced.
