As an option, you can choose to transpose selected audio clips along with any selected MIDI clips.
SONAR uses pitch-shifting to perform the transposition. You can transpose audio only a single
octave in either direction (-12 to +12), and you cannot transpose audio when you are using diatonic
transposition.
The Transpose dialog box contains the following fields:
Amount
The number in this field tells SONAR how many half-steps, up or down (depending on whether you
enter a positive or negative number), to transpose the selected data, unless you check the Diatonic
Math check box. If you select the Diatonic Math check box, 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:
