472 Chapter 20 Song Settings and Preferences
This mode tunes keys to different degrees of scaled tuning, and delivers a “key
signature character”. When playing mostly white keys (in the Pure setting, and with C as
the Root Key), C major will be the main focus, and tuning will be scaled to that chord.
An A major chord that is played immediately after a C major (and is therefore subject to
C major scaled tuning) will be affected somewhat by the scaled tuning effect, but will
not sound completely tempered. If you normally play polyphonic music, this mode
(when using the Pure setting) will sound most pleasing to your ears.
The Fixed Tuning scales are ideal for a number of Baroque and Mediaeval instruments
and styles of music.
User
Each semitone can be detuned from equal temperament in semitone steps. To do so,
just click-drag—vertically—on each semitone box until the desired value is reached.
Alternately, you can double-click in each semitone box, and type in a value. Press Enter
or click on another box to exit the text entry mode.
The Reset button will reset all of your tuning adjustments to their default values.
The Stretch Lower and Stretch Upper sliders can be used to stretch the tuning in the bass
and treble, to simulate the “stretched tuning” of some instruments, for example
acoustic pianos.
Stretch Lower determines the deviation from the equal-tempered scale in the bass end
of the sound. The higher the value, the further down the low notes are tuned. A setting
of 0 results in an equal-tempered scale tuning.
The Stretch Upper parameter does the same in the treble end of the sound.
