In Logic Pro and Logic Express, if you create a new song based on your Autoload Song or other template and try to open an existing Audio Instrument's user interface, the Freeze cursor may appear, even though the track isn't frozen. If you try to play the instrument live, you won't hear any sound.
Note: The freeze cursor is a unique cursor that only appears when you attempt to click on a parameter that cannot be altered when a track is frozen. You can see it in the following picture.
This happens if you've previously opened your Autoload Song or other template, frozen an existing Audio Instrument track in the song, and then closed the song without saving. If you subsequently create another song based on the same template, the Audio Instrument track will still behave as if it was frozen.
To resolve this issue, simply start and then stop playback, and the Audio Instrument should behave normally.
