Setup a Backup Machine
Depending on the situation, you would want to duplicate your show computer, so you would have a backup if a problem happens on the main computer.
To do so, you would need to synchronize these 2 machines together, to seamlessly switch from one to the other, if needed during the show.
For this tutorial, we will use Chataigne, so be sure to download it (version 1.6 minimum, so it supports spaces in OSC addresses). The last section covers 2 alternatives solutions.
Configure the Master Machine
The 2 computers will be configured, so one is the master (the main machine) and the other is slave (the backup machine).
On the main machine, there are 2 options to activate. Open the
CMD+K), then go to
OSC tab :
- setup a server that sends OSC to your slave machine (on port 12000)
This way, the main Millumin will send OSC to Chataigne every time a column is launched.
Please note that 12000 is the default port for Chataigne.
Configure the Slave Machine
On the backup computer, be sure to copy your Millumin project and load it.
device-panel, be sure the
input port is set to 5000 (no need to activate
API feedback or configure a server).
This way, this Millumin will receive orders from Chataigne to launch columns (depending on how columns were launched on the main machine).
Run Chataigne :
- add an
OSCmodule on the left of the interface
- set the
remote portto 5000 on the right of the interface
Launch some columns on the main machine : if Chataigne is correctly setup, the OSC icon will blink :
If everything is ok, add a
state (middle of the interface) with a
Then, configure the mapping :
Inputsection, select the element
Outputsection, add a
- set the custom-message as
- add a
Now, if you launch a column on the master Millumin, the slave Millumin will also launch this column.
Connect the Video Switcher
Lastly, connect the output of each computer to the video-switcher, and connect the output of the video-switcher to your videoprojector or screen.
If a problem happens, you would just have to use your video-switcher, to change the source to display on stage.
In the very same fashion as Chataigne, you could use Octopus, a free software that also feature a Millumin integration.
If you are a programmer, a script written in Python could also be a solution. If interested, please check this ZIP containing a basic script to do so :
