<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.

<h2 id="ace-a-b-switch-cross-fade">ACE A/B Switch and ACE Cross Fade</h2>
<p>
2023-01-03 10:35:08 -05:00
These two plugins are very similar and allow 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
2023-01-03 03:09:07 -05:00
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>
2023-01-03 10:35:08 -05:00
Both ACE A/B Switch and ACE Cross Fade will default to the A version. Using
an automation lane, it's switch to the B version and back. This is where the
difference between the two plugins comes into play.
</p>
<p>
2023-01-03 10:35:08 -05:00
With ACE A/B Switch, the switch is instant, it's either A or B:

<p>
2023-01-03 10:35:08 -05:00
With ACE Cross Fade, however, it's possible to gradually transition to the
B version and then back, mixing A and B signal in different ratios.

2023-01-03 10:35:08 -05:00
The plugins support 1-, 2-, and 4-channel configurations:
2023-01-03 03:09:07 -05:00
</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
</li>
</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>
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.

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.

<h2>Arpeggiators</h2>
<p>
Arpeggiators commonly take a chord and play it note by note in a certain
pattern: up (from the lowest note to the highest note), down (from the
highest note to the lowest one), up and down, down and up, or in a random
fashion.
</p>
<p>
They also have a number of additional settings like division that
defines the rate at which an arpeggiator will repeat the pattern. Or the
number of octaves the arpeggiator will jump between while transposing
a repeating note.
</p>
<p>
All three arpeggiators shipped with Ardour&nbsp;— simple arpeggiator, Barlow
arpeggiator, and Raptor arpeggiator&nbsp;— share these basic settings.
However, some of their design specifics vary.
</p>
<p>
The simple arpeggiator allows setting different velocities for notes at the
bar line, beat line, and subdivisions. It also has a swing setting.
</p>

The Barlow arpeggiator has sample-accurate triggering and automatically
adjusts to the current time signature. It also allows setting min and max
velocity.

The Raptor arpeggiator has harmonic controls, input pitch and velocity
tracking, and a few other features.
