Preparing Tracks for DestructivePunch Recording
In order for a track to be enabled for DestructivePunch recording, the track must contain a contiguous audio file that meets the following requirements:
*   
The file must start at the beginning (sample 0) of the session.
– and – 
*   
The File Length must be equal to or greater than the DestructivePunch File Length setting (see DestructivePunch File Length).
If a track does not contain a file that meets these requirements, you can do any of the following to meet the requirements:
*   
Move the current file in the track Timeline so that its beginning aligns with the session start.
*   
Use the Consolidate command to create a continuous file of the required length.
*   
Change the DestructivePunch File Length setting so that the current file is equal to or greater than the required length.
*   
Use the Prepare DPE Tracks command to consolidate audio on all DestructivePunch-enabled tracks. (See Using the Prepare DPE Tracks Command.)
