and the Play In/Out button in the Audio Punch-In tool blinks green).
Record Out is sent when recording begins (the Record button in the Audio Punch-In tool
blinks red).
Play Out is sent when recording ends and postroll begins (the Stop button in the Audio
Punch-In tool changes to blue).
Stop Out is sent when postroll ends (the position indicator stops moving).
