I have a vocal sample cd and everytime I load an instrument file it will load but it won't play back. When I play a key the "disk" light lights up red and I don't hear anything at all. I'm assuming this has something to do with the size or length of the sample (they're all around 10 seconds) because my percussion sample cd works fine. All the samples on it are very short. I've changed every setting I can find and nothing will make it play. Anyone have an idea what the problem is? I'm using Halion 2.
