382 Chapter 14 Recording in Logic Pro
MIDI region recording will behave as per usual, with new regions created for each
recording. When the Transport’s Cycle button is turned on, however, all MIDI region
recording will result in a single, merged region.
Retrospective Recording of MIDI Regions
If you played a great solo while playback was running, but weren’t in record mode—
don’t worry. Simply use the Capture as Recording key command. All events you played
(after the last playhead change) will be added to the recorded MIDI region—just as if
you had been in record mode.
Note: If you move the playhead before executing this command, the next incoming
event will delete all previously played events (and your solo will be lost forever).
Recording on Multiple MIDI Tracks
You may occasionally want to record multiple MIDI tracks at the same time. Often, this
will be data recorded from an external sequencer, or played from a keyboard that is
split across multiple MIDI channels.
You can also simply play the same MIDI channel information from your keyboard, but
record it to multiple tracks. One reason why you would do this is to create layered
instrument parts.
To record regions on several MIDI tracks:
m Switch on the Record Enable buttons of the tracks you wish to record to.
Note: Selecting an external MIDI or instrument track which is not record-enabled will
turn off the record-enabled status of all other external MIDI or instrument tracks.
Record-enabled audio tracks are not affected.
There are two operating modes available for simultaneous recording of multiple MIDI
tracks: Layer or Multiplayer recording.
 When Layer Recording: Incoming MIDI events are sent to all record-enabled MIDI
tracks. You can listen to all selected instruments before, and during, recording.
 A MIDI region is created on the selected track after recording.
 Aliases of the MIDI region on the selected track are recorded on the other tracks.
The advantage of this approach is that any subsequent edits to the “parent” MIDI
region will affect all aliases, ensuring that all layered tracks remain identical.
 When Multiplayer Recording: Incoming MIDI events are distributed to the various
record-enabled tracks, in accordance with transmitted MIDI channel numbers.
 The channel of the incoming event must correspond to the channel of a record-
enabled track, in order for this functionality to work.
 If no track with a corresponding channel number is found, the event will be routed,
and recorded, onto the selected track.
