Transpose dialog

The Process > Transpose command opens the Transpose dialog box, which allows you to transpose the pitches of MIDI and audio clips up or down by a fixed number of half-steps. It does so by changing the MIDI key numbers of note events and by pitch-shifting audio clips. Simply enter the number of half-steps in the Amount field of the Transpose dialog box; a negative number to transpose down, a positive number to transpose up. See To transpose selected events.

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 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 select 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 select this check box. SONAR transposes the selected data up or down, but only within the current key signature.

Transpose Audio

If you select 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 Platinum feature only).

Formant scaling. (this is a SONAR Platinum 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.
