Start the TouchOSC App and select the Layout for lightShark.

Configure the connection settings as follows.

Go back and press "DONE".

In the lightShark Preferences, in the MIDI&OSC tab, make sure that OSC is enabled and that the input and output ports are correctly configured.
Now from TouchOSC you can control the lightShark.

Connect the computer with Vezér to the same network as your LightShark device.
In lightShark within the preferences, in the MIDI&OSC tab make sure that OSC command reception is enabled and that the input and output ports are correctly configured.
In the Vezér preferences, add an OSC output by specifying the IP address and the LightShark input port,

Add a “OSC Flag” track.

Add a Keyframe and enter the command with the action you want to perform.
Below is an example of how to send the "GO" command to Playback 1:
/LS/Go/PB/1 <0>

Note that actions in LightShark are performed by releasing the button, so the message is sent on <0> value instead of <1>.
