A pitch range is louder than others.
Sometimes a filter or effect can cause resonance at a certain pitch that makes it louder than the others.
To reduce the volume at a particular pitch range:
- Click on the red (key scale) x-axis button on the Morph Panel. This will bring up the 3D envelope editor.
- Identify visually on the waveform surface the pitch range where the sound is too loud (should look higher contrast than the rest).
- Select the Axe tool.
- Mouse wheel up or down to change the size of the tool so you can chop all lines in the envelope at once.
- Chop the lines at just below the pitch region that is too loud.
- Chop in the middle of the pitch region that is too loud.
- Chop just above pitch region that is too loud.
- If there are any currently selected vertices in the envelope, press 'a' to deselect them.
- Shift + left-drag to box-select the new vertices at the middle of the pitch region.
- In the Vertex Params panel, drag left on the amp slider to reduce the amplitude of the envelope at that pitch.
