For example, if MIDI Merge mode is disabled, recording overwrites any existing MIDI data within the record range. Since the start and end times for recording are located within both of the existing clips, newly recorded notes are written into both of the existing clips, and into a new clip created to fill the space between them.
When selecting an entire clip, or a section within a clip, before punching, no new clips are created. In this instance, only the material residing within the existing clip changes, with no new material recorded outside the clip.
Unlike audio recording, MIDI recording in this scenario is destructive. Newly recorded MIDI data overwrites existing MIDI data while leaving the existing clip boundaries intact.
If the MIDI data within a clip is altered because of a record take, the original material is either lost (unless you choose Edit > Undo MIDI Recording) or combined with new material (if MIDI Merge was enabled during recording). If an existing clip contains material you want to keep, use Duplicate to make a copy of the clip (
Duplicating Clips), or duplicate the track’s playlist or record in a new playlist to keep a backup (see
Working with Playlists).
