Changing length of wav file

Hi,
What should be happening is that you are encapsulating your wav or “event” into a “part”. There is a dropdown for this “Events to Part” - It’s possible that the key shortcut is my customisation and has led you wrong. Any way, find “Events to Part”. It’s under the Audio Menu.

Parts can hold many events. Once in a part, you can drag the beginning and end of it to snap to barlines, beats etc according to your quantise setting. Now you can move or copy the entire part. it’s much easier than just working with events. I attach a screenshot to make things clearer. Hope this helps.
