<p>
Ardour offers two modes for interpolating automation control points: <kbd
class="menu">Linear</kbd> and <kbd class="menu">Discrete</kbd>. The mode is
changed by a <kbd class="mouse">Right</kbd> click on the automation lane header
and choosing the mode from the mode menu.

<p>
<kbd class="menu">Linear</kbd> mode interpolates values between control points
in a given automation curve by connecting them with straight lines; the values
played back are derived from the points that lie on the lines thus defined.
Typically, this is what is desired and is the default mode for all automation
lanes.
</p>
<p>
<kbd class="menu">Discrete</kbd> mode does <em>no</em> interpolation between
control points in a given automation curve. The values set by the control
points do not change until the following control point is reached at which
time the value is then set to its value; this continues on until there are no
more control points. Typically this is used for parameters such as mute or
sustain pedal (e.g., on a MIDI piano track).
</p>
<p class="note">
When recording automation via MIDI (e.g., pitch bend from a MIDI keyboard),
Ardour always uses discrete mode.
