Members will come in and out of your ensembles over time. You can adjust access to your folders in a couple of ways. The easiest way to remove access to a folder from a former member is to reset the passcode on their folder. The former member will no longer be able to access the folder, and if appropriate, you can give the new passcode and the folder name to a new member to use.
In addition to resetting a passcode for specific folders, you can also recall music from one or many folders from the Assign/Recall Music menu. Keeping your folders current ensures you always have your digital library ready to accommodate your needs.
