Solution
This issue is resolved in Logic Pro 7.1, which no longer has a 107 audio region limitation when importing OMF files.
For Logic 7.0:
The errors are linked to the number of Audio Regions the OMF file contains. If one track of the OMF file contains more than 107 Audio Regions, one of these errors may occur. In case of split stereo files, each channel's regions count separately. This means that the error will in this case occur with more than 53 parts of a split stereo file (which equals 108 regions).
An OMF file that will be imported into Logic Pro cannot contain more than 107 Audio Regions per track. You may reduce the number of Audio Regions per track by joining some of them with digital mixdown or bounce function before exporting the OMF file.
Because of this limitation, you should use the AAF format for data exchange between Pro Tools, AVID, and Logic Pro. FinalCut Pro sessions can easily be transferred using Logic Pro's FinalCut Pro XML im- and export function.
