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

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