• A director required for any metaconcert containing more than 3 participants.

• For an undirected concert, the maximum output is one and a half times the maximum output of the strongest participant. Each participant may contribute up to three quarters of their maximum output. A skill check must be passed to initiate the concert. If there's sufficient time, you can take 20 on this.
  
• If there is a director, the metaconcert output depends on his skill. I'll sort out some numbers therefore.
