Scala Files and tuning
What they do
The ARIA Player uses Scala files (SCL) to achieve many scales and temperaments. Scala files are a commonly used standard for defining scales and temperaments, and a number of common and historical tunings are already included with your installation. The common tuning standard of Equal Temperament is selected by default.

The tuning options chosen in the Settings view affect every instrument slot. In addition to setting an overall tuning system, instruments can be tuned individually using the instrument slot tuning controls.
- Click the Settings button. The Settings view appears.
- In the Tuning section, click the Set button
. The Please select Scala file dialog box appears.
- Scala files on Windows can be found in C:\Program Files\Garritan\ARIA Player\Scales.
- Scala files on Mac can be found in Macintosh HD/Applications/Garritan ARIA Player/Scales.
- Select the desired Scala file (SCL) and click Open.
- Click the Scala Center menu, and then select the base note for your selected temperament or scale.
Just intonation with C5 as a center will sound different than just intonation with E4 as a center. The octave designation that follows the pitch name is important when there are either more than 12 or less than 12 pitches within an octave.
- Click the Tuning menu to choose a pitch standard for A4 from the list, ranging from 380 to 451 Hz. By default, this is set to International 440 (A4 = 440 Hz).


Scala file reference
