Audio clips that are not all of the same bit depth.

SONAR X2 project files may contain new features that will be missing if opened in SONAR 4, including:

Clip effects and clip automation:

Automation envelopes are orphaned.

Groups:

SONAR X2 groups are preserved but will not be completely functional in SONAR 4.
