Apple Logic Pro 7 - Manual (Page 80)

80 Chapter 1 Using Logic
• Add tracks—will distribute the slices across multiple audio tracks, allowing you to
adjust the position or delete slices freely. The Number of additional Audio tracks panel
in the window determines how many tracks are used for the distribution of the slices.
These tracks are in addition to the original audio track, on which the Recycle file was
imported.
• Crossfade—All slices of the file are imported to the same track and automatically
crossfaded. The crossfade is equal powered. The length of the crossfade is
determined by the value (shown in milliseconds) displayed in the Crossfade length
panel.
• Render into single file—When importing Rex files this function writes all ReCycle slices
into a single audio file using the current Logic song tempo for the rendering process.
The adjustment of the numerical values is via use of the mouse as a slider, or double-
clicking on the panel(s), and direct numerical entry.
Audio Export and Import
Logic has the ability to export and import song contents using the OMF (Open Media
Framework, also known as OMFI—Open Media Framework Interchange), AAF, OpenTL
(Open Track List) and Final Cut Pro/XML file formats. These functions can be found in
Logic’s global File menu. There, you will also find various Track and Region Export
functions. The following section explains the use of Logic’s Export/Import functions.
OMF Export/Import
Typically, the OMF format is used for data exchange with Digidesign ProTools software.
The OMF file format only supports the exchange of audio data (audio media and the
usage of this audio media in a song)—MIDI and automation data will be ignored when
using the export functions.
OMF Export
To export the current song as an OMF file, select File > Export > Song as OMF File. This
will launch a dialog with the following options:
OMF File Version
This allows you to export the file in OMF Version 1 or Version 2 format. You will usually
choose Version 2 here. Version 1 is only useful for backwards compatibility with older
software versions.
Include Audio
If this box is checked, all exported audio files will be integrated into the OMF file itself
(Note: This can result in a very large file, and can make file export times very long). If
unchecked, only file references are written to the OMF file. If this method is used and
you wish to copy the OMF file to another hard disk, you need to ensure that all
referenced audio files are also copied.
