SC Preset buttons
Press these buttons to recall the corresponding presets. Each pre-
set contains a custom detuning of each note of the scale, and
memorizes the selected degree(s) of the scale (as programmed in
Global mode, see "General Controls: Scale" on page 202).
When no preset is selected, the default scale is automatically
recalled. This scale assigns a -50 cent value to all notes, and turns
all scale degrees off.
You can select an SC Preset, also by assigning the relevant func-
tion to the Assignable Footswitch.
To save the current scale programming, while in the Global >
General Controls > Scale page, choose the "Write SC Preset"
command from the page menu, and select one of the preset loca-
tions where to save the current settings.
Keyboard diagram
When Quarter Tone is checked, or a User scale is selected, this
diagram allows you to modify each note's pitch.
Scale lock icon
When locked, Scale parameters remain unchanged when select-
ing a different Performance or STS.
This lock is reset when turning the instrument off, unless you
write Global settings to memory (see "Write Global - Global
Setup dialog box" on page 212).
For more information on parameter locks, see "General Con-
trols: Lock" on page 203.
How to fine tune each note of the User
scale
When the User scale is selected, the keyboard diagram becomes
active. You can then change each note tuning in cents of a semi-
tone (within a range of ±99 cents, referred to Equal tuning). This
way, you can create a custom scale, you can save to a Perfor-
mance or STS.
Fine tuning values
After selecting the User scale, touch a note in the keyboard dia-
gram, and use the TEMPO/VALUE dial to adjust the selected
note tuning in cents.
Note: These settings can be saved to a Performance or STS.

How to program a scale in realtime using
an SC (Scale) Preset
When the Quarter Tone function is activated, you can choose
one of the four SC (Scale) Presets, by using the soft button that
appear in the display.
How to program a scale in realtime using a
footswitch
The Quarter Tone function allows you to program a custom
scale in realtime, for example those sudden scale change typical
of Arabic music. Changes are not saved anywhere, so the scale is
easily "wiped-out" when selecting a different Performance or
STS, an SC Preset, or when pressing the Quarter Tone pedal
again.
Note: You can create a custom scale, to be assigned to a Perfor-
mance or STS, simply by selecting and editing a User scale, and
saving any change to a Performance or STS. See "Scale" above.
You can assign the "Quarter Tone" function to a footswitch.
Gbl
1. Program a footswitch to be the Quarter Tone switch.
Simply go to the Global mode, and reach the "Controllers:
Pedals/Slider" page. There, you will find the "Pedal/Foot-
switch" parameter, to which you can assign the Quarter
Tone function.
While still in Global mode, select the Write Global-Global
Setup command from the page menu, to save these settings
to the Global (see "Write Global - Global Setup dialog box"
on page 212).
2. Lower some note pitches.
Keep the Quarter Tone pedal pressed. The keyboard will
not play at this time. Press the notes you want to lower a
quarter tone. Release the pedal.
3. Play with your new scale.
Notes you pressed on step 2 are now lowered of a quarter
tone.
4. Reset the original scale.
Press and release the Quarter Tone pedal again, without
playing any note. All pitches will be reset, and the scale
selected by the Performance, STS will be recalled.
