Name and save a checkpoint of the current script, selected takes and gaps. 3. Edit a line or continue recording through the normal project workflow. 4. Return to the checkpoint, filter changed lines and share a detailed change report. Keep line-by-line recording, take selection, Alt Take Rescue, recording tools, stitching, mastering and audio exports. Checkpoints do not alter your selections. WHAT TO KNOW Checkpoints are manifests, not audio backups. They do not copy or restore recordings, measure listening quality or export a mix.
