By default, all players in your project are added to all flows that originated in the project. You can assign players to and remove players from flows manually; for example, if the soloists in a choral work do not sing for an entire flow.
Note
If you remove a player from a flow, any notes you have already input for that player in that flow are deleted.
Procedure
Result
Players are assigned to the selected flow when the checkbox in their player card is activated, and removed from the flow when the checkbox is deactivated.
