Adjusting effect parameters with envelopesAn envelope is displayed in the data window for each effect parameter that you've chosen to automate. Envelope points represent
You can add points, adjust their positions, and change the fade curves between points to modify effect parameters and the transitions between them.
Note: When you automate an effect’s frequency parameter
—such as the modulation frequency parameter in the amplitude modulation effect — you may notice that the frequency changes are more apparent when moving through the lower frequencies. This is because frequency scales plug- ins use a logarithmic scale, but effect automation uses linear interpolation.To make the automated frequency changes sound more natural, change the fade curve types to change the interpolation rates between envelope points.
