In some instances, key messages will not reach plug-ins in Ableton Live on Windows, including UVI Workstation. There is a workaround that can be implemented to solve this problem.
To ensure key messages reach plug-ins in Ableton Live (version 6.0.9 or higher):
- Create a text file named Options.txt
- Add this line of text to the file:
-_EnsureKeyMessagesForPlugins - Put it in the following directory (Windows 8):
User\AppDataRoaming\AbletonLivex.x.xPreferences
Additional information about Live's Options.txt overrides here.
