Start at Center - Load SuperSitter on any track. The depth orb starts centered (neutral position). 2. Listen First - Play your track and ask: "Should this be upfront or in the background?" 3. Drag Forward - For vocals, leads, or anything that needs presence, drag the orb forward. Watch it grow and move closer as your sound moves forward in the mix. 4.
