meric keypad functions. You can always use the
numeric keypad to select and enter values in the
Event Edit Area, Edit Selection indicators, Main
and Sub Counters, and Transport fields.

the way Pro Tools worked in versions lower than

you can play up to two tracks of audio in Shuttle
Lock mode. Press the Start key (Windows) or Con-
trol (Mac), followed by 0–9 for different play
speeds. Press Plus (+) or Minus (–) to reverse di-
rection. Recall Memory Locations by typing the
Memory Location number, followed by Period (.).

you set a number of record and play functions, and
also operate the Transport from the numeric key-
pad. With the Numeric Keypad mode set to

port

direction. Recall Memory Locations by typing Pe-
riod (.), the Memory Location number, and Period

with the Enter key and stop playback with the 0
key on the numeric keypad. This is useful for
quickly starting and stopping playback when audi-
tioning loop transitions. The
Use Separate Play
and Stop Keys
option is only available in Trans-
port Numeric Keypad mode.

lected, Pro Tools automatically saves backups of
your Pro Tools session file while you work. Back-

Enter on the numeric keypad to add a
Memory Location marker.
