Program P1: Basic/Vector 1–1: Program Basic

Note that for many of the scales, the setting of the

Key

parameter, below, is very important.

Equal Temperament:

This is the most widely used

scale by far, in which each semitone step is spaced at
equal pitch intervals.

Equal Temperament allows easy modulation, so that a
chord progression played in the key of C sounds
roughly the same as the same progression played in
F#. Sacrificed, however, is some of the purity of
individual intervals offered by the scales below.

Pure Major:

In this temperament, major chords of the

selected key will be perfectly in tune.

Pure Minor:

In this temperament, minor chords of the

selected key will be perfectly in tune.

Arabic:

This scale includes the quarter-tone intervals

used in Arabic music.

Pythagoras:

This scale is based on ancient Greek

musical theory, and is especially effective for playing
melodies. It produces completely pure fifths, with one
exception, at the expense of detuning other intervals–
thirds in particular.

As much as Pythagoras might have like to do so, it’s
not possible to make all the fifths pure while also
keeping the octave in tune. For the sake of the octave,
one of the fifths–the interval from the sharp fourth
degree to the sharp first degree–is made quite flat.

Werkmeister

(Werkmeister III)

This scale was one of

the many temperament systems developed towards
the end of the Baroque period. These “Well-Tempered”
tunings were aimed at allowing relatively free
transposition–although you’ll still notice that the
different keys maintain their own distinct
characteristics, unlike Equal Temperament.

J.S. Bach was referring to these new scales in his title,
“The Well-Tempered Clavier.” As such, this group are
particularly appropriate for late baroque organ and
harpsichord music.

Kirnberger

(Kirnberger III)

This is a second “Well-

Tempered” tuning, dating from the early 18th century.

Slendro:

This is an Indonesian gamelan scale, with five

notes per octave.

When

Key

is set to

, use the C, D, F, G and A notes.

Other keys will play the normal equal-tempered
pitches.

Pelog:

This is another Indonesian gamelan scale, with

seven notes per octave.

When

Key

is set to

, use the white keys. The black

keys will play the equal tempered pitches.

Stretch:

This tuning is used for acoustic pianos.

User All Notes Scale:

This is a user-programmed scale

with different settings for all 128 MIDI notes. You can
set up this scale in Global mode (Global 3–1b).

User Octave Scale 00–15:

These are user-programmed

scales with settings for each of the 12 notes in an
octave. You can set them up in Global mode (Global 3–
1a).

Key (Scale Key)

[C…B]

Selects the key of the specified scale.

This setting does not apply to the

Equal Temperament

Stretch

, and

User All Notes

scales.

If you’re using a scale other than Equal
Temperament, the combination of the selected scale
and the

Key

setting may skew the tuning of the

note. For example, A above middle C might become
442 Hz, instead of the normal 440 Hz. You can use
the Global Mode’s

Master Tune

parameter to

correct this, if necessary.

Random

[0…7]

This parameter creates random variations in pitch for
each note. At the default value of

, pitch will be

completely stable; higher values create more
randomization.

This parameter is handy for simulating instruments
that have natural pitch instabilities, such as analog
synths, tape-mechanism organs or acoustic
instruments.
