AutoSave
This preference determines how the AutoSave
feature functions.
Enable Session File Auto Backup When this op-
tion is selected, Pro Tools automatically saves
backups of your Pro Tools session file while you
work. Use the Keep and Backup Every fields to
specify the total number of incremental backups
that are kept and how often the session is saved.
Online Options
Record Online at Time Code (or ADAT)
Lock When this option is selected, online re-
cording begins as soon as Pro Tools receives and
locks to time code or ADAT sync.
Record Online at Insertion/Selection When this
option is selected, online recording begins at the
Edit cursor location. Recording continues until
Pro Tools stops receiving time code. If you make
a selection, Pro Tools records online for the
length of the selection.
Open Ended Record Allocation
This preference determines how much of your
available hard drive space is allocated for record-
ing.
Use All Available Space When selected, the
drive’s entire available space is allocated. This
can sometimes slow down the recording process
for hard drives that use certain file systems, in-
cluding HFS+ and NTFS.
Limit To Sets the maximum allowable recording
duration. This can help reduce the time it takes
to begin recording by allocating only a portion
of your hard drive. The number of minutes spec-
ified is allocated for each record-enabled track.
You may want to experiment with this number
to achieve the recording performance you want.
Auto Regions Fade In/Out Length Sets a default
length for fade-ins and fade-outs automatically
applied to region boundaries. Using automatic
fade-ins and fade-outs saves you the trouble of
editing to zero-crossings or creating numerous
rendered fades in order to eliminate clicks or
pops in playback. Autofades are not written to
disk. Value range is from 0–10 ms for the Auto
Region Fade In/Out Length. A value of zero (the
default) means that no auto-fading will occur.
The Auto Fade value is saved with the session,
and is automatically applied to all free-standing
region boundaries until you change it.
Calibration Reference Level Sets a default cali-
bration reference level in dB when Pro Tools is
in Calibration mode.
Custom Shuttle Lock Speed (Pro Tools 6.2 and
Higher on Pro Tools|HD Systems) This option
sets the highest fast-forward Shuttle Lock speed
(key 9) for Shuttle Lock modes (Classic or Trans-
port). The range for this setting is 50–800%. For
more information, see “Custom Shuttle Lock
Speed” on page 244.
