A list of 'just intonation' ratios to show on the chart, separated by commas. Ratios can be simple math expressions like 5/4 or 2 * 3/2.

For example this input:

1, 3/2, 2, 2*5/4, 3, 4, 9/8 * 4

 
Will render charts for:
  • 1: low sa
  • 3/2: low pa
  • 2: middle sa
  • 2*5/4: a middle ga
  • 3: middle pa
  • 4: high sa
  • 9/8 * 4: a high re

Use the Up and Down arrow keys to adjust the current digit. Left / Right keys switch digits.

You'll need to specify the fundamental freq pretty accurately before the charts will make sense. Try Play fundamental to match the fundamental by ear.

Holding down the Ctrl key will let you adjust an oscillator by moving the mouse left and right
