 Performance Merge
From the Performance Merge display, you can collectively assign multiple Parts from the selected
Performance to empty Parts in the Performance currently being edited. For example, you can merge four
Piano Parts in one Performance and two Strings Parts in another Performance to create even more richly
textured, layered sounds.
This allows you to separately mute original Parts and newly added Parts.
