Record Section
Latch Record Enable Buttons
When selected, multiple audio tracks can be record-enabled. When not selected, multiple audio tracks cannot be record-enabled. Record-enabling an audio track takes all other audio tracks out of record-enabled mode.
Link Record and Play Faders
When selected, Pro Tools does not remember separate fader levels for tracks when they are record-enabled, allowing you to maintain the same monitoring level for tracks during recording and playback.
Audio Track RecordLock (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
This option configures Pro Tools tracks to either emulate a digital dubber, or to maintain legacy behavior for track record status.
*   
When selected, the record-enabled audio tracks remain record-enabled when playback or recording stops.
*   
When not selected, record-enabled audio tracks are taken out of record enable when Pro Tools is stopped. This prevents tracks from remaining armed from pass to pass, emulating track record behavior of a digital dubber.
Transport RecordLock (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
This option lets the Transport Record (the Record button in the Transport controls) be configured to either emulate a digital dubber, or to maintain legacy behavior for the Transport master Record.
*   
When selected, the Transport Record remains armed when playback or recording stops. This saves having to re-arm the Transport between takes, emulating digital dubber behavior.
*   
When not selected, the Transport Record disarms when Pro Tools is manually stopped or stops due to a loss of timecode. This replicates standard Pro Tools recording behavior.
The Transport RecordLock option is automatically disabled and grayed out when Destructive Record mode is enabled.
Disable “Input” When Disarming Track (In “Stop”) (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
For flexibility, TrackInput monitoring can be customized to remain selected regardless of track record status, or to automatically switch to Auto Input monitoring after a recording pass. This lets you optimize monitoring for a typical dubbing workflow (in which you might want tracks to remain in Input Only mode until explicitly switched to Auto Input monitoring) or a typical music tracking workflow (in which leaving a track in Input Only monitoring mode after recording can result in accidental double-monitoring).
*   
When selected, taking an audio track out of record enable (any mode) takes it out of Input Only mode, regardless of the global monitor mode, and switches it to monitor audio from disk only.
*   
When not selected, audio tracks remain in Input Only monitoring mode until explicitly switched to Auto Input monitoring.
Mute Record-Armed Tracks While Stopped (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
This setting determines monitor status of record-armed tracks.
*   
When selected, Pro Tools mutes all record-enabled tracks when the transport is stopped. Input can still be monitored while stopped using the TrackInput Monitor button.
*   
When not selected, Pro Tools does not mute audio input on record-enabled tracks when the transport is stopped.
PEC/Direct Style Input Monitoring (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
This option changes the way the TrackInput monitoring mode is indicated on-screen (and on supported control surfaces) to emulate “PEC” (playback) and “Direct” (input/bus) indication on some large format consoles.
*   
When not selected, the TrackInput button shows the letter “I.” The button remains gray to indicate Auto Input mode and lights green to indicate Input Only mode.
*   
When selected, the TrackInput button remains gray and shows the letter “D” to indicated Input Only mode (“Direct”); it lights green and shows the letter “P” to indicate Auto Input mode (“Pec” or playback).
Automatically Create New Playlists When Loop Recording
When selected, copies loop recorded alternate takes to new playlists in the track. This is especially useful to prepare for track compositing in Playlists view after loop recording multiple alternate takes.
Online Options
Record Online at Timecode (or ADAT) Lock
When selected, online recording begins as soon as Pro Tools receives and locks to incoming timecode.
Record Online at Insertion/Selection
When selected, online recording begins at the edit cursor location. Recording continues until Pro Tools stops receiving timecode. If you make a selection, Pro Tools records online for the length of the selection.
DestructivePunch File Length (Pro Tools HD and Pro Tools with Complete Production Toolkit Only)
This preference sets the duration of consolidated audio files when preparing tracks for DestructivePunch mode. The default value for this setting is 25 minutes.
