Tuning Tables
In addition to the standard equally divided octave tuning, Proteus X contains twelve
factory programmed tuning tables. The Keyboard Tuning parameter selects which
tuning is used by the current preset.
The factory keyboard tuning tables are described in the following table.
The Just C Tuning Tables
Well Tempered and Just were standard keyboard tunings up until the 20th-century when
the current “equal tempered” scale became prevalent. In an equal tempered scale, the
octave is equally divided into 12 parts. In Just or Well Tempered scales, the 12 notes are
separately tuned to produce pure chords. However, in Just tunings you are limited to
playing certain chords and if you play the wrong chord it may sound terrible!
Tuning tables can be changed as you play using a program change (create several presets
with the same sound and different tuning tables) or using a continuous controller (link
2 presets and crossfade between them using a controller).
The Just C2, Just C min, Just C3 Tuning Tables
Fully explaining the mysteries of just intonation is beyond the scope of this manual, but
the subject is covered exhaustively in Hermann Helmholtz’s On the Sensations of Tone,
available at most libraries and bookstores.

Description
Equal Temperament
Standard Western tuning
12 equally spaced notes per octave.
Just C
Just intonation. Based on small interval ratios. Sweet and
pure, non-beating intervals.
Vallotti
Valotti & Young non-equal temperament. Similar to 12 tone
equal temperament. Each key has a different
character for a given scale.
19-Tone
19 tone equal temperament. 19 notes per octave.
Difficult to play, but works well with a sequencer.
Gamelan
5 tone Slendro and 7 tone Pelog. (Javanese.) Pelog are
white keys, Slendro are black keys. Exotic tunings of
Gamelan flavor.

different.
Kirnberger
Another well temperament developed by Johann
Philipp Kirnberger where no pitch is more than 12 cents off
from equal temperament.
Scarlatti
A variant of Meantone tuning which was used from the 15th
to 18th centuries.
Repeating Octave
Middle C octave is repeated up and down the keyboard.
Link with a preset in equal temperament to form unusual
inversions up and down the keyboard.
