SONAR X1 project files may contain several new features that will be missing if opened in earlier versions. These
features will be lost permanently if resaved in an earlier version.
e Screensets
o Screensets saved in X1 projects will be unavailable in earlier versions
e View layouts and docking settings
o All docking and view specific settings from X1 will be lost when opening
e Toolbar settings
o Toolbar settings are not compatible with earlier versions of SONAR and will be lost
Re-saving a SONAR X1 project file in an older version may permanently remove the project data described above.
Template files saved from SONAR X1 will not load in earlier versions of SONAR. This is because of changes made to
SONAR's view persistence code in SONAR X1.
Windows Vista
The following issues are known problems with Microsoft Windows Vista (as of Vista SP1):
e In WDM or WASAPI mode for some audio devices, SONAR reports an "Unable to Open..." error when
attempting to record w/ multiple input drivers. This may occur when SONAR attempts to open more than one
input for recording when Allow Arm Changes During Record Or Playback is selected in Transport > Record
options. This problem is most likely caused by the driver disallowing multiple inputs to be used simultaneously.
e As of Vista SP1, WaveRT drivers for onboard audio devices do not work in Vista X64 while running the 32 bit
version of SONAR. This is due to a problem with WOW64 in Windows Vista X64 that has been reported to
Microsoft. This issue has been addressed by Microsoft Windows 7.
WASAPI Wave Profiling in Windows Vista
Prior to wave profiling in WASAPI we recommend that you profile your audio hardware at least once in WDM mode.
This allows the WASAPI wave profiler to pick up the driver preferred DMA settings from WDM.
This is required because some drivers perform better with these settings and WASAPI does not provide any mechanism to
get the driver preferred values. This issue has been addressed by Microsoft Windows 7.
Windows XP 64-bit
SONAR X1 utilizes new methods for GUI drawing which requires the WIC API. This is included in most service packs
for XP by default except for XP 64-bit.
SONAR X1 does not officially support Windows XP 64-bit operating systems, however XP 64-bit customers can install
X1 however these users must download the WIC API from Microsoft.
