<p>This window controls how the intonation curve is generated.
</p>

<p>Control group:</p>
<ul>
<li>Micro intonation:<br>Intonation generated by Special Transitions.
 It produces fast and localized pitch perturbations, and may not have a small amplitude.</li>
<li>Macro intonation:<br>Intonation with a global effect, generated by a specific intonation code.
The pitch variation is slower than the micro intonation.</li>
<li>Smooth intonation:<br>When enabled, the pitch between intonation points is calculated using cubic interpolation.
 When disabled, the interpolation is linear.</li>
<li>Random intonation:<br>When enabled, a set of intonation parameter values is chosen randomly. Each time a text is synthesized,
the generated intonation may be different from previous executions.</li>
<li>Intonation drift:<br>The drift adds a fluctuation to the pitch.</li>
</ul>

<p>Parameters group:<br>
If the checkbox "Use these parameters" is checked, the intonation will be generated using these parameter values
instead of the parameter values from the configuration files.
</p>

<p>Drift parameters group:<br>
These parameters control the drift generator. The deviation value is not necessarily the maximum amplitude,
because the signal is filtered by a lowpass filter. In other words, it may be necessary to set a deviation value that is
higher than the desired value.
</p>

<p>Operations:</p>
<ul>
<li>Set the parameters:<br>Click on "Update". If this button is not clicked, the changes will not have an effect.</li>
</ul>
