It is also not possible to record audio on frozen tracks. In fact, the Record button will be
hidden when a track is frozen.
Freeze Files
The temporary freeze files are saved in a folder named “Freeze Files” which is created in
the root directory of your project folder. Usually, you won’t need to access these freeze
files directly.
Logic manages these freeze files automatically in the background: They are created
during the Freeze process, will play back in place of the original tracks (as long as these
tracks are frozen), and will be deleted as soon as the Freeze button of the
corresponding track is deactivated.
In some cases, however, it might be handy to use freeze files directly: One example
would be if you wanted to freeze all of your tracks, and use the freeze files for a remix
in another studio (on DSP-based systems, for example).
Refresh Freeze Files
The Audio > Refresh Freeze Files menu function (and key command of the same name)
allow you to refresh the current freeze files. This may become necessary when global
changes are made that also affect the playback of the frozen tracks (tempo changes, for
example).
