title: OSC: Using the Setup Dialog
|
|
---
|
|
|
|
<p>
|
|
Starting with Ardour 5.1 OSC has a graphic setup dialog. This dialog
|
|
can be accessed from Preferences->Control Surfaces. Select OSC and
|
|
click on the Show Protocol Settings.
|
|
</p>
|
|
<p>
|
|
The Ardour OSC dialog has three tabs. The main tab, the Strip Types
|
|
tab and the Feedback tab.
|
|
</p>
|
|
<p>
|
|
Many OSC devices get their IP from a DHCP making it difficult to set
|
|
an IP in Ardour's OSC settings. Therefore, most of the settings are
|
|
<em>default</em> settings. Values are set and the next OSC surface to
|
|
send a /set_surface* message to Ardour will use those settings. An OSC
|
|
surface that has previously sent a message to Ardour will retain the
|
|
settings it already had. The <em>Clear OSC Devices</em> will reset all
|
|
device settings. A <em>/refresh</em> message will both reset the
|
|
device settings as well as set that device to any new settings. The
|
|
Use of <em>/set_surface</em> will override all settings except
|
|
<em>Port Mode</em>.

<h4>Connection:</h4>
|
|
<p>
|
|
This field is informational only. It shows where Ardour will receive
|
|
OSC messages. The system Name and the Port are the most important parts.
|
|
</p>
|
|
<h4>Port Mode:</h4>
|
|
<p>
|
|
This drop down allows the choice of Auto or Manual outbound port
|
|
setting. The default Auto port mode, will send OSC messages back to
|
|
the port messages from that surface are received from. This setting
|
|
allows two surfaces on the same IP to operate independently. However,
|
|
there are a number of OSC control surfaces that do not monitor the
|
|
same port they send from and in fact may change ports they send from
|
|
as well. Manual allows the outgoing port (the port the surface will
|
|
receive on, to be manually set. In Manual port mode only one control
|
|
surface per IP can work. Most phone or tablet OSC controllers like
|
|
touchOSC or Control need Manual port mode. More than one controller
|
|
can be used so long as each has it's own IP.
|
|
</p>
|
|
<h4>Manual Port:</h4>
|
|
<p>
|
|
This is an Entry box for setting the outgoing port when in
|
|
Manual port mode.
|
|
</p>
|
|
<h4>Bank Size:</h4>
|
|
<p>
|
|
This sets the default bank size for the next surface to send a
|
|
<em>/set_surface/*</em> OSC message. Bank size 0 (the default) sets
|
|
no banking and allows controlling all strips included in strip_types
|
|
at once.
|
|
</p>
|
|
<h4>Gain Mode:</h4>
|
|
<p>
|
|
Sets the faders (and sends faders) feedback math to position where a
|
|
value between 0 and 1 represents the fader position of the same fader
|
|
in the mixer GUI or dB where the feedback from fader movement will be
|
|
returned as a dB value. When the Gain Mode is set to position, the
|
|
/*/name feedback for the channel will show dB values in text while the
|
|
fader is being adjusted and then return the the name text.
|
|
</p>
|
|
<h4>Debug:</h4>
|
|
<p>
|
|
For debugging purposes this allows logging either good OSC messages
|
|
Ardour receives or invalid messages received or none.
|
|
</p>
|
|
<h4>Preset:</h4>
|
|
<p>
|
|
Ardour now allows the use of preset settings. The default settings
|
|
used are the settings from the last session or the factory defaults
|
|
the first time OSC is enabled. As soon as any of these settings are
|
|
changed, the Preset will change to "User" and the new settings will be
|
|
save to the osc directory Ardour configuration directory as
|
|
<em>user.preset</em>. This preset file can be renamed for future use.
|
|
It is suggested to also change the name value inside to avoid confusion
|
|
in the preset listing. Ardour will ship with some of it's own presets
|
|
that go with some popular OSC control and map combinations.
|
|
</p>
|
|
<h4>Clear OSC Devices</h4>
|
|
<p>
|
|
This button clears operating device profiles so that Ardour will reset
|
|
all devices settings to use the new defaults from changed settings. a
|
|
device may still override these new settings with the /set_surface set
|
|
of commands. The reason for setting defaults settings is that some OSC
|
|
controllers are not able to send more than one parameter at a time and
|
|
so having correct defaults allows one "Connect" button rather than 4.
|
|

<h3>Default Strip Types tab</h3>

|
|
This allows selecting which of Ardour's mixer strips will be available
|
|
for control. The Factory default is all strips except master, monitor
|
|
and hidden strips. If it is desired to only see input tracks the
|
|
others can be deselected. It is also possible to change these settings
|
|
from the control surface. A set of buttons could select showing only
|
|
inputs or only buses. If a group is selected in the GUI then showing
|
|
only selected strips will show only that group. Showing hidden tracks
|
|
is handy for cases where a groups of tracks that grouped to a bus or
|
|
controlled by a VCA are hidden, but one of those tracks needs a tweak.
|
|
</p>
|
|
<h3>Default Feedback tab</h3>
|
|
<p>
|

|
|
<p>
|
|
This allows setting up which controls provide feedback. The Factory
|
|
default is none. If the controller is unable to receive feedback, this
|
|
should be left blank. In the case of metering, Metering as a LED strip
|
|
only works if Metering as a Float is disabled.
