Table of Alternate keyboard tunings

Tuning Presets, compiled by Robert Rich

6.1.1

12 Tone Equal Temperament (non-erasable)

The default Western tuning, based on the twelfth root of two. Good fourths and  fths,

horrible thirds and sixths.

6.1.2

Harmonic Series

MIDI notes 36-95 re ect harmonics 2 through 60 based on the fundamental of A = 27.5

Hz. The low C on a standard 5 octave keyboard acts as the root note (55Hz), and the

harmonics play upwards from there. The remaining keys above and below the 5 octave

range are  lled with the same intervals as Carlos’ Harmonic 12 Tone that follows.

6.1.3

Carlos Harmonic Twelve Tone

Wendy Carlos’ twelve note scale based on octave-repeating harmonics.

A = 1/1 (440 Hz).

1/1 17/16 9/8 19/16 5/4 21/16 11/8 3/2 13/8 27/16 7/4 15/8

6.1.4

Meantone Temperament

An early tempered tuning, with better thirds than 12ET. Sounds best in the key of C. Use

this to add an authentic touch to performances of early Baroque music. C = 1/1 (260 Hz)

6.1.5

1/4 Tone Equal Temperament

24 notes per octave, equally spaced 24root2 intervals. Mexican composer Julian Carillo

used this for custom-built pianos in the early 20th century.

6.1.6

19 Tone Equal Temperament

19 notes per octave (19root2) offering better thirds than 12 ET, a better overall

compromise if you can  gure out the keyboard patterns.
