Sign an artist in
When an artist walks in, mark them as here. It records when they got in, and the crew can see they've arrived.
Step 1. On Me, press Today at the studio. It says how many people are still to sign in.

Step 2. Each booked artist is listed with their room. "Not signed in" or "was due 1:00 PM" means nobody has marked them yet. When they walk in, press Arrived.

Step 3. Marking them after they got in? It asks when: Just now, When it started or At the booked time. Pick one. If a label or company booked the session, it asks who actually walked in.

No host tonight? The engineer can press Arrived on the session itself. See Run a session.
