Which of the following are ways to free up a voice on a track?

• A. All of the above
• B. Deactivate the track
• C. Remove all of the track's output and send assignments
• D. Set the track's Voice selector to OFF

Answer: (A)

Freeing a voice means releasing a polyphonic resource that a software instrument uses to play notes, so another track or note can take over that slot. Deactivating a track stops all processing for that track, which immediately frees any voice it was occupying. Removing all of the track’s output and send assignments stops the track from routing MIDI or audio, so it can no longer contribute notes to a voice pool, freeing the voice for others. Setting the track’s Voice selector to OFF directly releases the voice slot that was allocated to that track, making it available again. Since each of these actions stops the track from consuming a voice, all of the above are valid ways to free up a voice.
