Channel device currently doesn’t have much functionality, and there isn’t an easy way for event binding to split or make a signal be for all players, so I think it would be perfect for that device to be able to convert a signal from a signal that has no instigation to one that does and vice versa.
Most needed example is to be able to send a signal that triggers on all players. For example, the ability to register all players to the audio player device, or teleport them all to a location.
