Sony Virtuoso: All Call
The attend button in the Virtuoso control panel has two functions.
By RIGHT-clicking on the Attend button, the instructor can force any students who have run the Soloist program to "attend" to the instructor console. Students who are running Soloist but have not clicked attend will appear in gray. Remember that only students who have clicked attend can be controlled by the instructor workstation.
By LEFT-clicking on the attend button, the instructor can remove students-- while the attend button is flashing, clicking on any attended student will remove them from the console, and close soloist on their workstation.
Click on the attend button again to turn off the flashing.
