The Speaker Indicator is a handy display feature that indicates which Element is being triggered. When auditioning Grooves and Sound Menu Elements, a Speaker Indicator appears next to the Element name.
In the picture above, the Elements, are grouped together in a large Favorites Suite. 124-Light Years Hyperscratch is the Groove being auditioned. The Speaker Indicator remains lit only while an Element is being triggered. Once the Element no longer plays, the Speaker Indicator disappears.
