<h2 id="ace-amplifier">ACE Amplifier</h2>

<p>
  This plugin can adjust gain by +/- 20dB anywhere in the processor box.
  It's typically useful in scenarios where a plugin's output needs to be
  adjusted, but the plugin does not provide its output level control.
</p>

<p>
  <em>Gain</em> is the only available setting. It can be set in the generic
  plugin editor dialog or adjusted on the respective automation lane.
</p>

<h2 id="ace-a-b-switch">ACE A/B Switch</h2>

<p>
  This plugin allows switching between two plugins earlier in the processing
  chain using an automation lane and custom pin connections.
</p>
<p>
  In the example below, the processor box for a 1-channel track has two
  <em>ACE Delay</em> plugins processing the input differently. Each plugin
  has one manually added output so that the original signal would flow into
  one instance of a plugin while bypassing the other one. All two resulting
  outputs then flow into the ACE A/B Switch plugin. Input 1 is considered the
  A version, input 2 is the B version.
</p>

<p>
  ACE A/B Switch will default to the A version. Using an automation lane, it's
  possible to momentarily switch to the B version and back.

<p>
  The plugin supports 1-, 2-, and 4-channel configurations:
</p>

<ul>
<li>Mono out: In 1/2 -&gt; Out 1</li>
<li>Stereo out: In 1/3 -&gt; Out 1, In 2/4 -&gt; Out 2</li>
<li>Quad out: In 1/5 -&gt; Out 1, In 2/6 -&gt; Out 2, In 3/7 -&gt; Out 3, In 4/8 -&gt; Out 4</p></li>
</ul>

<h2 id="ace-cross-fade">ACE Cross Fade</h2>

<p>
  This plugin allows gradual transitions between two plugins earlier in the
  processing chain using an automation lane and custom pin connections.
</p>
<p>
  In the example below, the processor box for a 1-channel track has two
  <em>ACE Delay</em> plugins processing the input differently. Each plugin
  has one manually added output so that the original signal would flow into
  one instance of a plugin while bypassing the other one. All two resulting
  outputs then flow into the ACE Cross Fade plugin. Input 1 is considered the
  A version, input 2 is the B version.

<p>
  ACE Cross Fade will default to the A version. Using an automation lane, it's
  possible to gradually transition to the B version and then back, mixing A and
  B signal in different ratios.

</ul>

<h2 id="ace-mute">ACE Mute</h2>

<p>
  This plugin can mute the signal anywhere in the processing chain as opposed
  to automating the mute state of the track that works on all processed audio
  only. Using <em>ACE Mute</em> in the very beginning of the signal chain means
  that in the muted state no signal is processed by plugins further in the
  processing chain.
</p>

<p>
  <em>ACE Mute</em> has no settings. All user interaction happens
  in the dedicated automation lane:
</p>

<p>
  Ardour also ships with a variation of <em>ACE Mute</em> called
  <em>ACE Slow Mute</em> that applies a 1 second long fade out/in before/after
  the muting.
</p>

<h2 id="voice-level-activate">Voice/Level Activate</h2>

<p>
  This plugin rolls the transport when the signal level on the plugin's input
  exceeds a user-defined level. A common scenario where this is helpful is
  recording in a home studio where an instrument or a vocal mic is at a distance
  from the computer. Arming a track for recording, toggling recording mode, then
  clapping in front of a mic or plucking a string will roll the transport and
  start recording to a track of choice.

<p>
  The only configurable setting is the input level threshold.
</p>

<h2 id="midi-note-mapper">MIDI Note Mapper</h2>

<p>
  Maps arbitrary MIDI notes to others. This affects both note-on and note-off
  events, as well as polyphonic key pressure. A single note can be mapped
  twice, but only the last mapping is used.
