The <dfn>Plugin Manager</dfn> provides a convenient interface to various

operations on plugins and is the primary troubleshooting tool when something
goes wrong with plugins. It works on both plugin files and the plugins index.

<h2>What is a plugins index?</h2>
<p>
For each type of a plugin (e.g. VST3 or AU) there are pre-configured paths
where these plugins are located. Every time Ardour runs, it re-scans plugins
in these paths and recreates an index — a kind of inventory of available
plugins. Whenever you open the <a href="@@plugin-selector">Plugin Selector</a>
dialog, Ardour reads the list of available plugins from that index and
displays them for you to pick.
</p>
<p>
Re-scanning paths is important because it's common for plugins to change on
the disk (e.g. when you installed a newer version) or get removed (when you
don't need a plugin anymore). Sometimes plugins get corrupted due to
a hardware failure. Indexing them often helps identifying issues early on,
and the Plugin Manager helps reviewing the general state of affairs with
plugins.
</p>
<p>
Ardour also treats LV2 plugins slightly differently and scans them on startup
unconditionally. You can disable the scanning of VST2, VST3, and AU plugins
entirely in the <kbd class="menu">Preferences</kbd> dialog.
</p>
<h2>Plugins info</h2>
The main part of the Plugin Manager window is the table where all plugins known
to Ardour are listed. You can use it to both view information about a plugin and
control some of its aspects:
<table class="dl">
<tr>
<th>Status</th>
<td>Ardour will displays the status of every plug-in file. See below
for more information</td>
</tr>
<tr>
<th>Ign</th>
<td>Do not load this plugin file at all</td>
</tr>
<tr>
<th>Fav</th>
<td>Set or unset the Favorite status for a plugin</td>
</tr>
<tr>
<th>Hide</th>
<td>Load this plugin file, but do not show it in the Plugin Selector</td>
</tr>
<tr>
<th>Type</th>
<td>The name of the API this plugin has been built with:
VST2, VST3, AU, LADSPA, LV2</td>
</tr>
<tr>
<th>File/ID</th>
<td>Displays the file name for LADSPA, VST2, and VST3, as well as
the ID for LV2 and AU</td>
</tr>
<tr>
<th>Name</th>
<td>User-visible name of the plugin</td>
</tr>
<tr>
<th>Creator</th>
<td>Developer of team of developers who created the plugin</td>
</tr>
<tr>
<th>Tags</th>
<td>Metadata that classifies the plugin by type,
2022-09-17 07:21:29 -04:00
e.g. 'instrument|synth' or 'analyzer'</td>
</tr>
</table>
<p>
The Status field specifically has the following options:
</p>
<table class="dl">
<tr>
<th>OK</th>
<td>The plugin file has loaded without any issues and the information
in the cache about it is up to date</td>
</tr>
<tr>
<th>New</th>
<td>The plugin file has just been discovered and successfully loaded
for the first time</td>
</tr>
<tr>
<th>Updated</th>
<td>The plugin file changed on the disk, the plugin cache has been updated
accordingly, the plugin file loaded successfully</td>
</tr>
<tr>
<th>Concealed</th>
2022-06-17 11:10:06 -04:00
<td>A VST2 plugin will be hidden from Plugin Selector, if a corresponding
VST3 plugin exists. The same applies to LV1 (LADSPA) and LV2</td>
</tr>
<tr>
<th>Error</th>
<td>There was a problem loading the plugin file</td>
</tr>
<tr>
<th>Stale</th>
2022-06-17 11:10:06 -04:00
<td>A plugin changed on the disk but hasn't been re-scanned
by Ardour yet</td>
</tr>
<tr>
<th>Incompatible</th>
<td>Scan the plugin failed. Typical reasons are 32/64-bit mismatch,
attempt to load a .dll on Linux or a .dylib on Windows</td>
</tr>
</table>
<p>
The <kbd class="menu">Plugin Count</kbd> section in the sidebar provides
basic information on available plugins: how many plugins of every supported
type are available through Ardour in total, how many failed to load, and
how many are missing.
</p>
<h2>Searching</h2>
<p>
2022-06-17 11:10:06 -04:00
You can search for a specific plugin or a group of plugins. Simply place the
cursor inside the input text box in the upper left corner and type. Ardour
will search in the index
</p>
<p>
By default, Ardour will search through plugin names, makers, and file names.
Additionally, you can search through Type, Tags, and Paths.
</p>
<h2>Scan actions</h2>
