Fix unwanted pitch fluctuations with copied envelope points
In cases where a resynthesized sound has unwanted pitch fluctuations, you can resolve
these artifacts by reducing the PVar (pitch variation) control on the source A/B/C/D
subpage. The downside with this approach is that each partial is aligned with its harmonic
tuning which may change the character of the sound significantly. Try this alternative
method.
1. In Logic Pro, make sure the Overall and Tune buttons are active, then select a single
Partial envelope point.
2. Click the Breakpoint button, and choose Copy from Breakpoint from the pop-up menu.
3. Click the Breakpoint button, and choose Paste All Breakpoints Pitch Data from the pop-
up menu.
The partial pitch values of the copied envelope point are applied to all other envelope
points, thus retaining the inharmonic features of the copied point while simultaneously
eliminating fluctuations from one point to the next.

Source components are shown only in advanced view. Click the Advanced button to
switch to advanced view, then click the A/B/C/D button to view detailed parameters for the
selected source.
The source edit window is opened by clicking the Edit button on any source subpage. Click
the close window icon (X) at the top right to close the window.
Use the Spectral button at the top of the Main edit window to open the Spectral edit
window.
Spectral edit window: Use to graphically edit spectral resynthesis data. You can also create
new sounds by using simple paint tools directly in the display.
Spectral data is displayed as follows in the Spectral edit window, or “canvas”.
• Time, expressed in seconds, is represented along the x-axis from left to right. It is also
shown at the pointer position.
