3 In Ardour terminology, a <dfn>processor</dfn> is anything which treats the
4 signal in some way and gets plugged into a mixer strip.
5 Ardour provides several builtin processors such as the fader or panners.
6 Processors can also be <dfn>plugins</dfn> used for effects or as instruments, as well
7 as sends or inserts which are affect <a href="/signal-routing/">signal
9 The arrangement of processors is arbitrary, and there is no limit to how
13 The main box in the top half of a mixer strip shows the <dfn>processor
15 Processors are shown as coloured rectangles, with a small "LED" beside
16 them that lights up when the processor is enabled. The colour of the
17 processor depends on its location in the sequence; processors that are <dfn>pre-fader</dfn> are
18 coloured in red, and <dfn>post-fader</dfn> processors are coloured green
19 (in the default theme).</p>
21 The processor box will always contain a blue <dfn>Fader</dfn> processor.
22 This indicates where in the processor chain the main channel fader is
23 located—this is the fader shown in the lower half of the strip.
25 <h2>Adding Processors</h2>
27 Processors can be added to the chain by
28 <kbd class="mouse">Right</kbd>-clicking in the processor list, This does three things:
31 <li>A gap is opened up to indicate the location of the click. The gap
32 shows where any new processors will be inserted.</li>
33 <li>The processor under the click is selected.</li>
34 <li>An options menu is presented.</li>
37 From the menu, new processors can be inserted.
40 <h2>To Reorder (Move) Processors</h2>
42 Processors can be re-ordered using drag-and-drop. Dragging a processor
43 allows it to be moved around within the chain, or copied to another
44 processor list on another track or bus.
47 <h2>To Enable/Disable a Processor</h2>
49 To the left of the name of each processor is a small LED symbol; if this
50 is lit-up, the processor is active. Clicking on it will deactivate the
51 processor and effectively bypass it.</p>
53 <h2>Removing Processors</h2>
55 Context-click on the processor you want to remove, and select <kbd
56 class="menu">Delete</kbd>, or <kbd class="mod3 mouse">Right</kbd>-click on it.
