Editing a Quarter Tone sub-scale (SC Preset)
Quarter Tone scales (SC Presets) are custom scales where detuning can be
activated or deactivated while playing. Changing note tuning while playing
is typical of Middle East/Arabic music. The detuning interval is usually next
to a quarter tone.
You can save up to four Quarter Tone scales into the SC (Scale) Presets.
The SC Presets are global and do not change with Keyboard Sets, Styles or
Songs.
