Educators would like a way to set the instrument, voice-type or ensemble for an assignment so that their students do not have to select that when launching an assignment.
While this feature is not available yet, there is a workaround using the Custom Levels feature. You can create a custom level for your class(es) and then configure that custom level for the assignment. When you create the custom level, you have to specify at least one instrument/voice-type and a range for that instrument/voice-type. If you only configure a range for one instrument/voice-type, then that instrument/voice-type will be automatically be selected when the student launches the assignment. You can learn more about custom levels here.
