When an advanced sequence is open in Output mode, audio controls are available for each active track along with a slider for adjusting the combined output of the three tracks. The border color of each set of controls matches the color of the track in the sequence: green for NAT, blue for SOT, and purple for Voice. The NAT, SOT, and Voice controls are enabled or disabled depending on the position of the position indicator. For more information, see
Working with Audio Tracks in Advanced Sequences.
The following illustration identifies controls in the Audio pane when an advanced sequence is open in Output mode, Mix Mode is set for Stereo, and the position indicator spans all three tracks.
