Personal monitoring can allow a performer with a smart phone to set
|
|
their personal monitor mix for a floor wedge or in-ear monitoring.
|
|
In Ardour 5.6 OSC commands to allow this were added.
|
|
</p>
|
|
<h3>Setup</h3>
|
|
<p>
|
|
Some setup needs to be done in the GUI mixer window before this can
|
|
work.
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Create a bus for each performer who will have personal
|
|
monitoring. A good practice is to name the bus with the
|
|
performers name.
|
|
</li>
|
|
<li>
|
|
Connect the output of that bus to one of the audio
|
|
interface's playback ports that is not otherwise used. OSC
|
|
will now include this bus in it's list of aux busses as it
|
|
no longer has it's output connected to the Master bus.
|
|
</li>
|
|
<li>
|
|
Add an aux send to each channel the performer needs to hear
|
|
in their personal mix. Many performers only need three or
|
|
four sources to be mixed. If the performer needs to hear a
|
|
a set of inputs that are combined into a bus, adding the
|
|
aux send to that bus may make more sense than adding ten
|
|
drum channels for example.
|
|
</li>
|
|
<li>
|
|
If the performer wishes to hear effects in their monitor,
|
|
an extra send from the send bus, placing the performers aux
|
|
send after the effect or a plugin can be added in line in
|
|
the aux bus itself.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
This gives stage or studio monitoring for the performer.
|
|
</p>
|
|
|
|
<h3>The OSC commands and feedback for personal monitoring</h3>
|
|
<p>
|
|
All of the personal monitoring commands and feedback start with a
|
|
<em>/cue</em>. It is expected that a surface used as a personal
|
|
monitor control will use only <em>/cue</em> commands.
|
|
</p>
|
|
<p>
|
|
Most phone OSC applets (TouchOSC, Control) require manual port to be set.
|
|
There are certainly more controls than needed. Using send enables for
|
|
example, may lead to wasted time discovering why a send has no sound.
|
|
A good easy to use controller that fits on most phones while still
|
|
being controllable even with big fingers might look like:
|
|

</td>

</tr>
|
|
</table>
|
|
|
|
<p>
|
|
Ardour is not limited to talking to one personal monitor controller
|
|
at a time, but is able to deal with many simultaneously, each controlling
|
|
it's own Aux bus.
|
|
</p>
|
|
<p class="note">
|
|
The send controls and feedback all have the send id (1 to n) in line
|
|
as part of the OSC path. So the path for the second send would be
|
|
<em>/cue/send/fader/2</em> to set the level. It is considered that
|
|
most surfaces used for this will only be able to handle one parameter.

While a fader is being adjusted, the corresponding <em>/*/name</em>

text will give the level in db.
