Global Playback Limit

If the new sound, music, or motion object is not killed or sent to virtual voice at the Actor-Mixer or Interactive Music level, it passes to the second process at the Master-Mixer level. At this level, a global playback limit is used to restrict the total number of voices that can pass through the bus at any one time.

Managing playback limits can be done in the advanced setting of any sound object, Actor-Mixer, or audio bus in the Advanced Settings tab of the Property Editor.
