MMCSS task profile support

The Multimedia Class Scheduler Service (MMCSS) provides Windows multimedia programs, including Music Creator, with prioritized access to CPU resources for time-sensitive processing.

By default, Music Creator uses the MMCSS task profile named Pro Audio. If desired, you can instruct Music Creator to use a custom MMCSS task profile.

To use a custom MMCSS task profile in Music Creator

1.	Determine the name of the MMCSS task profile that you want to use. MMCSS task profiles are listed in the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks. Ensure that the registry entry exists for the profile you want to use.

2.	If you have added any new profiles, reboot your computer to allow the MMCSS service to see the new profiles.

3.	In Music Creator, go to Edit > Preferences > Audio - Configuration File.

4.	Under Configuration Settings, click Edit Config File.

The Aud.ini file opens in the default Windows text editor.

5.	In Aud.ini, locate the entry called MMCSSTaskKey and set it to the desired profile name. For example:

MMCSSTaskKey=Pro Audio

6.	Save Aud.ini and close the Windows text editor.

7.	Click Reload Config Settings to reload the current audio configuration settings from Aud.ini.

Music Creator will now use the new task profile for MMCSS.
