Undo History dialog
Math check box (see below). If you check Diatonic Math, the number in this field tells SONAR how
many scale steps to transpose the selected data.
Diatonic Math
If you check this check box. SONAR transposes the selected data up or down, but only within the
current key signature.
Transpose Audio
If you check this check box. SONAR transposes any selected audio data up or down, but only by
half-steps, not diatonically.
• Type. Choose the type of audio data you’re transposing (this is a SONAR Producer feature
only).
• Formant scaling. (this is a SONAR Producer feature only) possible values range from -2.000 to
2.000 octaves. Formants give a voice its characteristic sound. You can use the Formant Scaling
value to offset the pitch transposition you’re applying. For example, if you’re transposing the pitch
down, you can raise the formant to try and maintain the characteristics of the sound.

Undo History dialog
The Edit > History command opens the Undo History dialog box, which displays a history of your
editing actions (the command is greyed-out if you made no edits). You can set how many editing
actions you want the Undo History dialog box to store by changing the number in the Maximum
Undo Steps field. The default value is 128.
Use the Undo History dialog box to jump to a previous time in the history of the project. Then you
can continue from that point, causing all the edits you did after that action to disappear.
The Undo History dialog box has the following fields:
History list
The History list displays a list of all the editing actions you did to this project, up to the number of
actions in the Maximum Undo Steps field.
To revert to an earlier version of a project, highlight the entry in the History list that represents the
point to which you'd like to return, and click OK. SONAR performs the necessary undo or redo
actions to take you to that point. Once you make any new edits, SONAR clears the History list of all
the edits you made after the edit you jumped back to. Then, as you do further work, the History list
grows again. Any edits that happened after the edit you jumped back to remain on the list.
