Which action will free up a voice on a track?

• A. Muting the track, if the Mute Frees Assigned Voice option is enabled
• B. Deactivating the track
• C. Removing all of the track's output and send assignments
• D. Setting a track's voice selector to OFF

Answer: (D)

In Pro Tools, the engine tracks a limited number of polyphonic resources called voices, and each track can be assigned to a voice to participate in polyphonic playback. To free up a voice, you must remove the track from occupying any voice. Setting the track’s voice selector to OFF does exactly that: it tells the system the track is no longer using a voice, so one voice is released back to the pool for other tracks to use. Muting can only free a voice if the option that allows a muted track to free its voice is enabled; otherwise, the voice remains allocated. Deactivating the track or removing all outputs and sends don’t guarantee freeing a voice, since they don’t directly change the track’s voice allocation.
