Recording
The OMF file supplies the following data and information:
• Tracks
• Clip positions—an OMF file's EDL edit resolution can be either frame
accurate or sample accurate. SONAR can read either, but always
writes sample accurate. The clip position is specified in absolute
samples.
• Slip edits
• Fades and crossfades (as destructive edits)—SONAR renders any
fades when it writes OMFs, creating separate clips for any fade-ins or
fade-outs. SONAR slip-edits the original clip to make room for the fade-
in and fade-out clips. If you export to an audio program that supports
slip editing, the user can delete the fade clips and roll out the original
clip to return to the original raw audio (without fades) if desired.
• Sample rate and audio bit depth, but only if the media are embedded in
the OMF
The OMF file does NOT supply the following data and information:
• Volume and pan envelopes—OMF does actually support limited
automation. However, as with Nuendo and most other OMF host
programs, gains and pans are ignored (on both read and write) in
SONAR as they are only supported on MONO tracks (OMF limitation).
• Plug-in effects.
•MIDI data
•Tempo
Whoever supplies the OMF file that you want to open in SONAR should
also send along a text file containing all pertinent information about the
project, especially tempo.
To Open OMF Files in SONAR
1. Use the File-Open command, which opens the Open dialog.
2. In the Files Of Type field, select OMF File.
3. Navigate to the folder that contains your OMF files, select the OMF file
you want to open, and then click the Open button, which opens the
Unpack OMF dialog.
4. If you know the exact tempo of the file, enter it into the Initial Tempo
field. It is always preferable to know and enter the project tempo at this
point. If you don't know the project tempo you can open the file at the
