20 <h2>Generic Plugin Editor</h2>
23 If a plugin does not have its own GUI, Ardour will construct a
24 <dfn>generic plugin editor</dfn> from a small set of common control
25 elements. Ardour will do this even for plugins that have their
26 own, if <kbd class="menu">Edit > Preferences >
27 GUI > Use Plugins' own interface instead of Ardour's</kbd> is disabled.
31 The generic UI can be temporarily switched to by <kbd class="mouse">right</kbd> clicking on
32 a processor and selecting <kbd class="menu">Edit with generic controls</kbd>.
33 This is necessary in order to access the <a href="@@automation">plugin
34 automation controls</a>.
38 In the generic UI, any controller can be reset to its default state by
39 <kbd class=mod3n></kbd><kbd class=mouse>Left</kbd>-clicking on it.
42 <h2>Analysis Graph</h2>
45 At the bottom of the generic plugin editor, clicking the arrow displays the
46 <dfn>Analysis Graph</dfn>.
52 <li>the <span style="background-color:black; color:white;">transfer function</span> in white,</li>
53 <li>the <span style="background-color:black; color:red;">phase response</span> in red (optional),</li>
54 <li>the <span style="background-color:black; color:green;">post effect spectrum</span> in green.</li>
58 The <dfn>transfer function</dfn> plots the output amplitude of the plugin (considered
59 as a "black box") against its input amplitude, along the audio spectrum.
62 The <dfn>phase response</dfn>, that can be switched on or off using the
63 <kbd class="option">Show phase</kbd> checkbox, plots the phase of the
64 plugins output against its input phase, along the audio spectrum. The scale is
65 shown in <span style="background-color:black; color:yellow;">yellow</span> on
69 The green spectrum plots the <dfn>output signal spectrum</dfn>, after the plugin
70 (for tracks that have a signal on).
73 The <kbd class="menu">dB scale</kbd> selector in the bottom left allows to
74 change the vertical scale of the graphs.

82 The MIDI keyboard in instruments plugins
87 The generic UI provides, for all MIDI instruments plugins, a keyboard, that can
88 be used either with the mouse, or by using a QWERTY keyboard as a piano. Both the
89 channel and the velocity can be set above the keyboard.
