===Method 2: Set a tuning using a Scala scale file and keyboard mapping file===

[Briefly: A Scala scale file is used to establish a tuning's octave or [[~~equave~~]], its interval relationships, and other properties. A Scala keyboard mapping file is used to set the tuning's base note, tuning center ~~or tonic~~, and keyboard map. The Scala format scale files and keyboard mapping files together work to ....

*Note that without a Scala keyboard mapping file (.kbm) also loaded, the resulting tuning may not be what you expect. Surge XT like most synths will assume a default tuning center frequency and keyboard mapping that sets the first note specified in the tuning file as MIDI Note C.60 and the tuning center (diapason, reference pitch) as international ISO standard pitch (MIDI A.69=440.000Hz). [Or will it? Seems undocumented. In fact, it does not. Default in Surge XT 1.2.3 is a base note of C.60 and the reference pitch is C.60=261.626Hz, which is close to but not international standard.] However, if for example we are using a just intonation scale and music with a tonic of F (F4, MIDI note 65, 349.23 Hz), we need to ensure the base note is set to the tonic F, and ideally will use a keyboard mapping file to do that.

[Or will it? Seems undocumented. In fact, it does not. Default in Surge XT 1.2.3 is a base note of C.60 and the reference pitch is C.60=261.626Hz, which is very close to but not exactly international standard.] However, if for example we are using a just intonation scale and music with a tonic of F (F4, MIDI note 65, 349.23 Hz), we need to ensure the base note is set to the tonic F, and ideally will use a keyboard mapping file to do that.

*Remember that when you load a Scala scale file you should always prevent mistuned surprises by loading a keyboard mapping file, if your instrument supports that. Or your instrument may let you set a base note for your tuning as described in the Method 2 Notes below, "Alternatives for setting the tuning's base note and tuning center." To learn more details about how to use Scala scale and keyboard mapping files, including what to do when your instrument doesn't offer the option to load a keyboard mapping file, see [[User:Mousemambo/Tuning methods#Tuning files|Tuning methods]].

'''''Alternatives for setting the tuning's base note and tuning center'''''

* Some software, like Garritan's Aria Player sampler system [and the Vital synth IIRC], ~~support~~ Scala scale files but do not support loading Scala keyboard mapping files. However, they do allow you to set the base note of the Scala scale file and its pitch. This fulfills two of the functions of the keyboard mapping file and you should use this method if it's all your instrument supports. If you are using a just intonation, for example, then setting the Scala scale file's base note to the music's tonic is essential.
