GPI Signal Sequences
GPI signal sequences differ, depending on whether or not you are using the Audio Punch-In tool with
preroll and postroll.
When you use the Audio Punch-In tool without any preroll or postroll, the following occurs:
Record Out is sent when recording begins.
Stop Out is sent when recording (and playback) ends.
When you use the Audio Punch-In tool with preroll and postroll, the following occurs:
Play Out is sent when preroll begins (the position indicator begins moving in the Timeline, 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).
n
Record Out and Play Out repeat if you perform additional recordings.
Trigger Signal Sent When

Recording with the Audio Punch-In tool ends but playback
continues because a postroll value is set in the Audio Punch-In
tool (that is, the signal is sent when the Stop button in the Audio
Punch-In tool changes to blue).
Record Out Recording with the Audio Punch-In tool begins.
Stop Out Playback stops.
