Video - GP6 editing: Copy / Paste

The copy/paste function lets you edit your scores/tabs more quickly by duplicating the bars you want to repeat in your piece. This option works in monotrack or multitrack. The multitrack option allows you to copy/paste bars from all the tracks of your score/tab in one action 

Note that you can also copy/paste additional information into your score/tab (diagrams, text and automations) or copy/paste between two projects.
