SONAR X2 can load projects from any previous versions of SONAR, but projects that are saved in
SONAR X2 cannot be re-opened in SONAR 1.x or SONAR 2.x. In case you need to open a pre-
SONAR X2 project in an earlier version of SONAR, it is recommended that you always create a
backup copy of the original project before you re-save the project in SONAR X2.
Project files saved in SONAR X2 will not open in SONAR 4 or earlier if they reference or include any
of the following types of data or information:
• 32-bit and 64-bit audio clips, including clips and tracks that have been frozen or rendered as 32-
bit or 64-bit data.
• Audio clips that are not all of the same bit depth.
Project files saved in SONAR X2 will not open in SONAR 5 if they reference 64-bit audio clips.
Project files saved in SONAR X2 that contain multiple automation envelopes per track may appear
like automation data is missing when opened in an earlier version of SONAR. To see all automation
data for a track right-click on it and choose Envelopes > Show Track Envelopes and then select
each envelope that you would like to show.
SONAR X2 project files may contain new features that will be missing if opened in SONAR 5 and
earlier, including:
• ACT current context.
• All AudioSnap data.
• Automation Read Enable States.
• Clip lock properties.
• Preserve mix between gang members setting.
• Synth Rack Assignable Controls.
• Synth Rack Automation.
SONAR X2 project files may contain new features that will be missing if opened in SONAR 4,
including:
• Clip effects and clip automation:
• Effects are removed.
• Automation envelopes are orphaned.
