QuickPunch and TrackPunch are nondestructive recording modes. Instead of replacing audio while punching, QuickPunch and TrackPunch create new audio files for each pass (a pass is one cycle of starting and stopping the Transport).Pro Tools begins recording a new audio file when playback begins, automatically generating clips in that file at each punch-in and punch-out point. Up to 200 of these “running punches” can be performed in a single pass. QuickPunch and TrackPunch provide instantaneous monitor switching on punch-out.After recording with QuickPunch or TrackPunch, the new audio clips appear in the Clip List. This includes the whole-file audio clip encompassing all punches from the record pass, along with the clips derived for each punch.Names for the punched clips are numbered consecutively starting with “01.” For example, if QuickPunch is used to punch in twice on a track called “Lead Gtr,” a clip for the parent audio file appears and is named “Lead Gtr_01,” and two clips for the punches are named “Lead Gtr_01-01” and “Lead Gtr_01-02.”If you stop playback and record additional punches with QuickPunch (or TrackPunch), a new whole file clip is created (since one is created for each pass), and subsequent clips are named by incrementing the first two digits in the name. For example, on the second pass, the punched clips are named “Lead Gtr_02-01,” “Lead Gtr_02-02,” and so forth.DestructivePunch is a destructive recording mode which permanently replaces pre-existing track material with newly recorded “punch” audio. Pro Tools only records while tracks are punched in, inserting new material and replacing audio in the track playlist.
