Creating a Track with the Next Channel Strip/MIDI Channel
The Track > New with Next Channel Strip/Instrument command (which has a
corresponding key command) can either create a new track, or a new track and a new
channel strip. The behavior of the command is dependent on the selected track type:
• If the selected track is an audio or software instrument track, the command creates a
new track below the selected track, and assigns the next channel strip to it. If no next
channel strip exists, one is created automatically.
• If the selected track is a MIDI track, the command behaves exactly as Track > New with
Next MIDI Channel. A new track is created, and assigned to the next MIDI channel.
Copying Tracks and Moving Regions
Hold down the Option key when moving a track vertically (click-drag the track number)
to create a copy of the track at the destination position. All selected regions on the source
track are moved to the new track.
Note: If you hold down the Option key before grabbing the track number, no further
regions on the track are selected. If no regions were selected in the first place, an empty
track (assigned to the same channel strip as the original track) is created at the destination
position.
If the Cycle function is turned on, all regions within the cycle are moved from the old
track to the new track. The musical result is unchanged, as the new track is a copy, and
therefore inherits the channel strip output setting of the source track.
In other words, only one channel strip is used for multiple tracks. This allows you to
double-track parts to thicken them up. It also makes tasks such as creating unison voicings
(an octave apart) simple and quick for software or MIDI instrument tracks.
To do this, Option-drag the regions on the destination track to replicate/restore them on
the source track.
Note: Altering the level (or other parameters) of the channel strip, regardless of which
track is selected, affects all tracks routed to the channel strip.
Creating Tracks for Overlapping Regions
The Track > New for Overlapped Regions function creates new tracks for wholly or partly
overlapped regions. The regions are redistributed across the newly created tracks. The
number of new tracks is equal to the number of overlaps. All tracks use the same channel
strip assignment as the original track.
As above, only one channel strip is used for all tracks.
