|
|
The <dfn>Foldback section</dfn> is an optional feature that provides stage monitoring mixes.
|
|
Many times the main mix is used for this purpose is a setup with only the control room. However,
|
|
for a separate studio and multiple monitor mixes for in-ear use, a separate set of Foldback
|
|
buses provides that flexibility.
|
|
</p>
|
|
<p class=note>
|
|
The Foldback bus was added in Ardour Version 6.0.
|
|
</p>
|
|
<p>
|
|
These foldback buses may be mono for a stage monitor wedge or stereo to allow
|
|
in-ear or headphones to have different mixes for each ear, such as one's self in one
|
|
ear and the rest of the music in the other.
|
|
</p>
|
|
<p>
|
|
A Foldback bus can be created in the same manner as any other bus is created, from the
|
|
<kbd class="menu">Track > Add Track, Bus or VCA</kbd> Window. Once at least one
|
|
Foldback bus has been created, the Foldback strip will appear in the mixer window.
|
|
</p>
|
|
<p>
|
|
Foldback sends can be created From the processor box context menu by selecting
|
|
<kbd class="menu">New Foldback Send</kbd> and then the Foldback bus desired.

|
|
A second method is to select all the source channels and then use the Foldback
|
|
bus sendbox context menu and select either <kbd class="menu">Assign Selected Tracks</kbd>
|
|
or <kbd class="menu">Assign Selected Tracks and Buses</kbd>.
|
|
</p>
|
|
<p>
|
|
The <kbd class="menu">View > Mixer: Show Foldback Strip</kbd> checkbox will determine if the
|
|
Foldback strip is visible. The Foldback strip appears Just to the left of the Master strip in the
|
|
Mixer window. It comprises:
|
|
</p>
|
|
<ol>
|
|
<li>Previous and Next buttons</li>
|
|
<!--li>Detach/attach control. This separates the Foldback strip into its own floating window</li-->
|
|
<li>Hide button</li>
|
|
<li>Foldback bus name button</li>
|

<li>Foldback bus output routing</li>
|
|
<li>Comments button</li>
|
|
</ol>
|
|
|
|
<h2>Previous and Next</h2>
|
|
|
|
<p>
|
|
The Previous button shows the previous Foldback bus in the Foldback strip.
|
|
The Next button shows the next Foldback strip. The button will be disabled
|
|
if there are no more Foldback buses in that direction.
|
|
</p>
|
|
|
|
<h2>Hide</h2>
|
|
<p>
|
|
The hide button hides the Foldback strip when not being adjusted.
|
|
The Foldback strip can be shown again from the main menu
|
|
<kbd class="menu">View > Mixer: Show Foldback Strip</kbd> item.
|
|
</p>
|
|
|
|
<h2>Name button</h2>
|
|
<p>
|
|
The name button shows the name of the current Foldback bus. It has two
|
|
menus the Foldback bus selection menu, activated with a mouse button 1
|
|
click and the context menu, activated with a mouse button 3 click. The
|
|
context menu has these items in it:
|
|
</p>
|
|
<ul>
|
|
<li><kbd class="menu">Comments</kbd> is the same as the Comments button
|
|
at the bottom of the strip</li>
|
|
<li><kbd class="menu">Outputs</kbd> shows the output routing grid</li>
|
|
<li><kbd class="menu">Save as a template</kbd> opens the template save
|
|
dialog. The template saved has the same number of channels and the same
|
|
processors but does not have any sends selected.</li>
|
|
<li><kbd class="menu">Rename</kbd> shows a rename dialog that allows the Foldback
|
|
bus name to be renamed</li>
|
|
<li><kbd class="menu">Active</kbd> toggles The active status of the current
|
|
Foldback bus</li>
|
|
<li><kbd class="menu">Protect Against Denormals</kbd> turns on denormal
|
|
protection for the current Foldback bus</li>
|
|
<li><kbd class="menu">Remove</kbd> will remove the current Foldback bus</li>
|
|
</ul>
|
|
|
|
<h2>Invert Buttons</h2>
|
|
<p>
|
|
The invert buttons (one for each channel) invert the audio signal. This
|
|
may be useful in some situations for controlling feedback. However,
|
|
proper microphone and monitor placement or the use of head phones
|
|
or in ear monitoring will be more effective.
|
|
</p>
|
|
|
|
<h2>Show Sends</h2>
|
|
<p>
|
|
Show sends allows the send levels and pan to be controlled from the
|
|
originating track by using the main fader for the track. The fader and
|
|
pan controls will change color to indicate this mode and the show sends
|
|
button will flash to indicate this mode. Changing the current Foldback
|
|
bus will disable this mode.
|
|
</p>
|
|
|
|
<h2>The Send Box</h2>
|
|
<p>
|
|
The send box shows controls for each send. There is a context menu available
|
|
by clicking mouse button 3 anywhere in the send box.
|
|
</p>
|
|
<ul>
|
|
<li><kbd class="menu">Assign Selected Tracks</kbd> creates Foldback sends on each
|
|
selected track that feed the current Foldback bus</li>
|
|
<li><kbd class="menu">Assign Selected Tracks and Buses</kbd> creates Foldback sends on each
|
|
selected track and bus that feed the current Foldback bus</li>
|
|
<li><kbd class="menu">Copy track/bus gains to sends</kbd> Sets the gain on the send to be the
|
|
same as the gain of the track or bus the send comes from for the current
|
|
Foldback bus</li>
|
|
<li><kbd class="menu">Set sends gain to -inf</kbd> sets the gain on all sends
|
|
for the current Foldback bus to −∞ (the lowest gain possible)</li>
|
|
<li><kbd class="menu">Set sends gain to 0dB</kbd> sets the gain on all sends
|
|
for the current Foldback bus to 0dB</li>
|
|
</ul>
|
|
|
|
<h3>The Send Control Block</h3>
|
|
<p>
|
|
<img src="/images/foldback-send.png" alt="The Foldback send">
|
|
</p>
|
|
<p>
|
|
There is a send control block for every send to the current Foldback
|
|
bus. The Send control block features three controls:
|
|
</p>
|
|
<ul>
|
|
<li>The button which shows the Foldback bus' name, has an active "LED"
|
|
indicator that can be clicked to enable or disable that send and has
|
|
a menu (mouse button 1) with items for that send:
|
|
<ul>
|
|
<li><kbd class="menu">Copy track/bus gain to send</kbd> Sets the gain
|
|
on the send to be the same as the gain of the track or bus the send
|
|
comes from for the current Foldback bus</li>
|
|
<li><kbd class="menu">Set send gain to -inf</kbd> sets the send gain
|
|
for the current Foldback bus to −∞ (the lowest gain possible)</li>
|
|
<li><kbd class="menu">Set send gain to 0dB</kbd> sets the send gain
|
|
for the current Foldback bus to 0dB</li>
|
|
<li><kbd class="menu">Remove This Send</kbd> removes the send from the
|
|
sending track or bus.</li>
|
|
</ul></li>
|
|
<li>The knob, only present on a stereo Foldback bus, which controls
|
|
the pan azimuth</li>
|
|
<li>The horizontal slider which control the level input from that channel</li>
|
|
</ul>
|
|
|
|
<h2>The Pan Control</h2>
|
|
<p>
|
|
This is just like every other track or bus strip and works the same way.
|
|
</p>
|
|
|
|
<h2>The Processor Box</h2>
|
|
<p>
|
|
This processor box is the same as on the other tracks and buses and allows
|
|
for adding things like reverb to the Foldback mix without writing it to the track.
|
|
It would also be possible to add in sound from a reverb bus instead.
|
|
</p>
|
|
|
|
<h2>The Listen Button</h2>
|
|
<p>
|
|
This is only available in PFL or AFL mode as it uses the same code as
|
|
the solo on other tracks and buses. It allows the control room monitor
|
|
or headphones to hear what the performer will hear in their monitor.
|
|
</p>
|
|
|
|
<h2>The Foldback Level Knob</h2>
|
|
<p>
|
|
This controls the output level being sent to the stage monitor.
|
|
</p>
|
|
|
|
<h2>The Output Port Selector</h2>
|
|
<p>
|
|
This is similar to the output selectors on the tracks and buses. It
|
|
differs in only a few ways. First it is never automatically connected.
|
|
A Foldback bus is always meant to be directly connected to an output
|
|
device and never to master or the monitor bus. The choices shown
|
|
Therefore reflect this.
|
|
</p>
|
|
<h2>The Comment Button</h2>
|
|
<p>
|
|
Just like the track and bus comment button, this allows opening a
|
|
window to type in notes about the current Foldback bus for future
|
|
reference.
