Constructor Detail

ScalaFile

public ScalaFile(java.lang.String desc,
                 double[] notes,
                 java.lang.String[] names)

Create a new Scala file object.

Parameters:

desc - The description of the tone scale.

notes - The pitches (notes) used in the scale.

names - The names of the notes used (or null).

ScalaFile

public ScalaFile(java.lang.String desc,
                 double[] notes)

Create a new Scala file object.

Parameters:

desc - The description of the tone scale.

notes - The pitches (notes) used in the scale.

ScalaFile

public ScalaFile(java.lang.String scalaFile)

Reads a Scala file from disk and returns a new instance.

The Scala scale file format: This file format for musical tunings is becoming a standard for exchange of scales, owing to the size of the scale archive of over 3700+ scales and the popularity of the Scala program.

Usually it has .scl as extension.

Parameters:

scalaFile - The Scala file to read.

Method Detail

write

public void write(java.lang.String scalaFile)

Writes a Scala file to disk. The peaks use cent values.

The Scala scale file format: This file format for musical tunings is becoming a standard for exchange of scales, owing to the size of the scale archive of over 3700+ scales and the popularity of the Scala program.
