21 <h2>Generic Plugin Editor</h2>
24 If a plugin does not have its own GUI, Ardour will construct a
25 <dfn>generic plugin editor</dfn> from a small set of common control
26 elements. Ardour will do this even for plugins that have their
27 own, if <kbd class="menu">Edit > Preferences >
28 GUI > Use Plugins' own interface instead of Ardour's</kbd> is disabled.
32 The generic UI can be temporarily switched to by <kbd class="mouse">right</kbd> clicking on
33 a processor and selecting <kbd class="menu">Edit with generic controls</kbd>.
34 This is necessary in order to access the <a href="@@automation">plugin
35 automation controls</a>.
39 In the generic UI, any controller can be reset to its default state by
40 <kbd class=mod3n></kbd><kbd class=mouse>Left</kbd>-clicking on it.
46 This is a rarely used section that displays the contents of the description
53 This section displays CPU time measurements for the currently opened plugin.
54 For more information, please see the documentation on the
55 <a href="/troubleshooting/plugin-dsp-load/">Plugin DSP Load window</a>.
58 <h2>Analysis Graph</h2>
61 At the bottom of the generic plugin editor, clicking the arrow displays the
62 <dfn>Analysis Graph</dfn>.
68 <li>the <span style="background-color:black; color:white;">transfer function</span> in white,</li>
69 <li>the <span style="background-color:black; color:red;">phase response</span> in red (optional),</li>
70 <li>the <span style="background-color:black; color:green;">post effect spectrum</span> in green.</li>
74 The <dfn>transfer function</dfn> plots the output amplitude of the plugin (considered
75 as a "black box") against its input amplitude, along the audio spectrum.
78 The <dfn>phase response</dfn>, that can be switched on or off using the
79 <kbd class="option">Show phase</kbd> checkbox, plots the phase of the
80 plugins output against its input phase, along the audio spectrum. The scale is
81 shown in <span style="background-color:black; color:yellow;">yellow</span> on
85 The green spectrum plots the <dfn>output signal spectrum</dfn>, after the plugin
86 (for tracks that have a signal on).
89 The <kbd class="menu">dB scale</kbd> selector in the bottom left allows to
90 change the vertical scale of the graphs.

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