Though my sound libraries have been loaded on an external hard drive and they show up in my DAW (Logic Pro), they all sound fine once loaded up which takes time but many times recently, once the track is bounced in placed or bounced out completely it sounds choppy, kind of like the samples didn't loaded even though they did load up. I had already waited for the full bar to load up. It has started happening with my String Ensemble Library and more recently on my Piano Libraries as well.I was super surprised when this happened even on a track that used very little CPU. How do I prevent fro happening?
