Scale Type
Selects the basic scale.
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 music 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 liked 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 C, 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 C, 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 (G–USER SCALE> ALL).
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 (G–USER SCALE> OCTAVE).
10
[Equal Temperament...User Octave 15]
Key (Scale Key)
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 (GLOBAL> BASIC)
parameter to correct this, if necessary.
Random
This parameter creates random variations in pitch for each note. At
the default value of 0, 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.
