The scale features in this new version of FretFind are now mostly finished.

To use them:

• Browse to the "Preferences" page on the left, choose one of the options and click save.
• Browse to the "Scale" page and edit your scale. If you are working in Equal Temperament you can choose the number of tones in an octave (fractional values like 12.5 or 10.375 work fine). If you are working in the Scala mode you can choose a scale from the archive or create your own.
• Browse to the "Listen" page. To hear the scale quickly, click "Play Ascending", or create your own sequence of notes and chords by checking the checkboxes. Click "Play Sequence" to hear your creation.

The latest development is available for download here. You may view the ChangeLog.
