The difference between active and observer seats on Virtuoso live sessions on the Virtuoso Stage.
An observer seat means that you can watch the live session on the Virtuoso Stage. You can select different camera views and type in the live session chat box.

An active seat means that you can interact directly with the host with your webcam and microphone. You'll appear on the screen wall and have a unique perspective through a camera below the screen that you're on. So an artist like Carl Cox can walk right up to you and speak to you directly as if you were there together.
