- Audio Aux? say what? I am sure most people will have noticed that they
- can find no <em>Aux</em> strips in the Ardour mixer. There are none.
- There are busses that can be used a number of ways. From analog days,
- in OSC, a bus is something that gets used as a sub mix before ending up
- going to Master. An auxiliary bus is used like a separate mixer and
- its output goes outside the program or computer to be used as:
- a monitor mix, a back up recording, or what have you. In OSC where
- controller strips may be limited, it may be useful not to use up a
- strip for an aux that is not really a part of the mix. It is also
- useful to get a list of only aux busses if the control surface is a
- phone used to provide talent monitor mix control on stage. Each
- performer would be able to mix their own monitor. The user is free
- to enable both busses and auxes if they would prefer.
+<h3 id="hidden">Using hidden strips</h3>
+<p>
+ Ardour allows any of it's strips to be hidden so that they do not show
+ up on the GUI mixer or editor. OSC follows the GUI by default and will
+ not show hidden strips. As of Ardour 6.0 the OSC commands include
+ <kbd class="osc">/select/hide <em>y/n</em></kbd> for the selected
+ strip and <kbd class="osc">/strip/hide <em>ssid</em> <em>y/n</em></kbd>
+ for any strip. This allows the control surface to hide or unhide a strip.
+ What may not be obvious is that hiding a strip makes it disappear and
+ become unselected. So if a selected strip is hidden, it is no longer
+ selected and the select channel will show the default select strip
+ (Master). In order to show a hidden strip, the hidden strips need to
+ be shown first using the <kbd class="osc">/set_surface/strip_types 512</kbd>
+ command to show only hidden strips. Then use the
+ <kbd class="osc">/strip/hide <em>SSID</em> 0</kbd> or
+ <kbd class="osc">/select/hide 0</kbd>
+ to show that strip. Of course, because only hidden strips are showing,
+ the strip you have set to no long hide will seem to vanish. A
+ <kbd class="osc">/set_surface/strip_types 159</kbd> will then show
+ the default strip types or replace the 159 with the desired strip_types.
+</p>
+<p class="note">
+ When hiding more than one strip in a row, check the strip name before
+ hiding as the strips will move as each strip is hidden just as it does
+ with the GUI mixer. So to hide strips 5, 6 and 7, the hide button
+ for <code>ssid</code> 5 is pressed 3 times. A more intuitive method
+ would be to hide strips from right to left (7, 6 and 5) which will
+ work as expected.
+<p>
+ In short, shown strips can only be hidden when they are viewable and
+ hidden strip can only shown (or un-hid) when strip_types include hidden
+ strips.
