Here's a new one: In Logic 9, when I record midi or audio info, I can hear my track back fine. But as soon as I edit that region (by shifting, copying, cutting, etc.) the audio sound disappears! When I go into the piano roll editor, or sample editor, I can hear what's there, and can fool around with the notes/samples). But back in the Arrange window, I can't hear anything! The only way to regain audio, is to quit Logic and boot it up again. Then the sound is back. Any ideas or suggestions would be greatly appreciated.
