Audio processing and functions
Envelope display
Shows the shape of the envelope curve over the wave-
form image of the audio selected for processing. Envelope
curve points above the center line indicate positive pitch
shift, while curve points below the center line indicate
negative pitch shift. Initially, the envelope curve will be a
horizontal, centered line, indicating zero pitch shift.
• You can click on the curve to add points, and click and
drag existing points to change the shape. To remove a
point from the curve, drag it outside the display.
Curve Kind
These buttons determine whether the envelope curve
should consist of spline curve segments (left button),
damped spline segments (middle button) or linear seg-
ments (right button).
Spline curve segment envelope
The same envelope with damped spline segments selected.
The same envelope with linear segments selected.
Range
This parameter determines the vertical pitch range of the
envelope. If set to “4”, moving a curve point to the top of
the display corresponds to pitch shifting by +4 semitones.
The maximum range is +/-16 semitones.
Transpose and Fine Tune
These parameters allow you to adjust the value of a curve
point numerically:
1. Click on a curve point to select it.
The selected point is shown in red.
2. Adjust the Transpose and Fine Tune parameters to
change the pitch of the curve point in semitones and
cents, respectively.
Pitch Shift Mode
These are the same parameters as on the Transpose tab,
see “Pitch Shift Mode” on page 209.
Example
Let’s say that you wish to create a pitchbend effect, so
that the pitch is raised linearly by exactly 2 semitones in a
specific part of the selected audio.
1. Remove all curve points by clicking the Reset button.
2. Select a linear curve by clicking the Curve Kind button
to the right.
3. Make sure the Range parameter is set to 2 semitones
or higher.
4. Create a point where you want the pitchbend to start
by clicking on the envelope line.
Since this is the starting point for the pitchbend, you want its pitch to be
zero (the envelope line should still be straight). If necessary, use the Fine
Tune parameter to set the curve point to 0 cents, because this point gov-
erns the start point, where you want the pitch transition to begin.
5. Create a new curve point at the horizontal position
where you want the pitchbend to reach the full value.
This curve point determines the rise time of the pitchbend effect, i.e. the
further away from the starting point the new point is positioned, the
longer it will take for the pitchbend to reach the full value, and vice versa.
6. With the second point still selected, use the Trans-
pose and Fine Tune parameters to set the pitch to exactly
2 semitones.
