Let's create a rehearsal mode that can be initiated from a live meeting. The presenter will share prepared content (ex: conducting video) that streams audio and video while all participants follow along to sing/play their part in the piece of music. During that time, the presenter (conductor) will use a special listen button that is only active during rehearsals. The listen button will "un-mute" one performer at a time from the list of participants to allow the conductor to check parts. Microphones will remain muted from participant to participant. This will eliminate problems with sound delay due to variations in internet speed. Note: the presenter (conductor) must remember to "mute me" when sharing rehearsal content so the performers do not hear part checks when the conductor clicks the listen button.
