• 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.

Clear button

You can click the Clear button in the Undo History dialog box to erase the undo history for the

current project and free up some memory. If SONAR is low on memory, it may offer to erase the

History list.

Maximum Undo Levels

This field lists the number of previous edits that SONAR stores. The default value is 128. You can

enter a smaller number to reduce the memory required.
