Build the Audio page

In the part we will focus on the Audio page.
First, tasks to set the level of the Timeline music and Audio group Stereo

• We create tasks to Mute/unmute V-nodes audio outputs.

*VN01 and VN02 will have audio file playing at the same time, this way we can switch from main audio/spare seamless.

• In these tasks, we add Leds device to get the information in the UI of which V-node is muted/unmuted the audio.
