Apple Logic Pro 9 - Manual (Page 441)

Record-Enabling Tracks
You can make recordings only on record-enabled—or armed—tracks, irrespective of
which arrange track is selected in the track list. There are a number of ways to enable
tracks for recording. You can enable tracks individually, or you can enable tracks
collectively—if they each have unique inputs. You can also enable several tracks that are
routed to the same channel strip. On occasion, you may need to enable audio and MIDI
tracks simultaneously. Each track or channel strip has its own Record Enable button, which
is used to arm that track or channel strip for recording.
Note: If the Record Enable button is not visible in the track list, choose View > Configure
Track Header (or use the corresponding key command), and select the Record Enable
checkbox. If this checkbox is selected and the button is still not visible, activate the relevant
audio hardware in Logic Pro > Preferences > Audio > Devices.
Record-Enabling Audio Tracks
You can activate the Record Enable buttons only of audio tracks that have a unique input.
Simultaneous arming of multiple tracks that use the same input (chosen in the Input slot)
is not possible.
If several arrange tracks are routed to the same channel strip (“Audio 1,” for example),
the new audio file will be recorded to the selected track (routed to “Audio 1”). If none of
these tracks are selected, but they are record-enabled, audio will be recorded to the first
(the top) of these tracks.
Space is reserved on the hard disk for armed tracks, which will no longer be available for
Undo files. For this reason, Logic Pro automatically disarms audio tracks when you are
editing in the Sample Editor, or if the hard disk is nearly full.
To enable one or more audio tracks for recording
Do one of the following:
µ
Click the Record Enable button on the desired track (or tracks) in the track list.
µ
Click the Record Enable button on the desired channel strip (or channel strips) in the
Mixer.
µ
Select the desired track (or tracks) in the Arrange area and use the Record Enable Track
key command, default assignment: Control-R.
