1A Scale Type: In addition to the usual equal temperament scale, 11 other scales, including a
user-definable scale, are available.

When Arabic is used and the Scale Key is "C," the notes E and B are lowered by 52 cents (RAST
DO/BAYATI RE). Changing the Scale Key allows you to select other scales. The following table
shows the scales and keys frequently used in Arabic music.

1C–1F User Scale: This scale allows you to define your own personal tuning scale. The tuning of each
keyboard note can be adjusted 99 cents on LCD screens 1C to 1F. To edit one of the preset scales,
first copy it (1G), then edit it as a user scale.
The User Scale settings are used by both the main and the sub.
1G Copy Scale: This is used to create your own scale based on one of the preset scales. The scale
selected here is copied to the user scale to enable you to edit it using pages 1C–1F.
1H Sub Scale: It is possible to switch between two scales, main and sub, using a pedal switch
connected to a keyboard such as the X3.
If MIDI message [Bn, 04, 00–3F] (Controller #04 is set to 0–63) is received, the main scale is
selected. If the MIDI message [Bn, 04, 40–7F] (controller #04 is set to 64–127) is received, the
sub scale is selected. In Combination mode, scales can be selected by any Timbre. In Multi mode,
they can be selected by any Track. So, for example, you could have one Timbre playing the melody
with the Arabic scale, and another Timbre playing the backing with an Equal Temperament scale.
• User scale settings are shared by the main scale and sub scale.
