Long time Acid user, but I am new to Melodyne. It seems every time I close Acid Pro 10, then re-open, all of my progress in Melodyne mysteriously vanishes without a trace. I tried to circumvent this by bouncing to wav, but as soon as the file finishes rendering, a neverending echo noise begins until I open a new acd file. The rendered track is empty. It seems any tracks including Melodyne are un-renderable. Has anyone else encountered anything like this?
