I recently upgraded to Protools 12 and am finding that when I work in older sessions from an external hard drive the audio will disappear when I move a clip from one area of the edit field to another. I have attached a video clip to illustrate. I don't seem to have this issue while working in new sessions. Is it just an issue data transfer speed from my G Drive? It's maddening.
