SONAR can also perform diatonic transposition, which shifts all the notes up and down the major
scale of the current signature by the designated number of steps. For instance, if you specify an
amount of +1 and the key signature is C-major, a C becomes a D (up a whole step), an E becomes
an F (up a half step), and so on. Diatonic transposition assures you that the transposed notes fit with
the original key signature.
As an option, you can choose to transpose selected audio clips along with any selected MIDI clips.
SONAR uses pitch-shifting (a plug in for changing audio pitch) 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.
To Transpose Selected Events
1. Select the tracks, clips, or events you want to transpose.
2. Choose Process > Transpose to display the Transpose dialog box
Figure 84. The Transpose dialog.
3. Use the spinners or enter the number of semi-tones to transpose.
Or
Use the + and - keys on your keypad to go up or down by one or [ and ] to go up or down by
octaves.
4. Check Diatonic Math if you want to transpose along the major scale of the current key.
5. Choose Transpose Audio if you want to pitch-shift selected audio clips. If you check this check
box. SONAR transposes any selected audio data up or down, but only by half-steps, not
diatonically. When this check box is enabled, the following two options become available:
• Type. Choose the type of audio data you're transposing. Choose options based on the
source material: single voice or instrument versus a group of instruments (ensemble or
polyphonic), and how long you want to wait for processing to finish: better quality can take a
long time if you're processing several tracks.
• Formant scaling. 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.
6. Click OK when you are done.
