I would have liked to have seen full backwards compatibility with cda4. The inability to drag tracks together and create your own segues is a real downer. As a frequent poster to this forum I would have liked to have been involved in the development of cda5. Cda4 was elegantly simple and very intuitive as to its use. Cda5 is certainly something else. I deleted my post from yesterday because it was sent off without enough thinking on my part. I don't mean to be so negative but this program reminds me too much of Vegas. Who wants to do audio work with a video program? As someone who spent money on sound forge 4.5, cda 4.0, Vegas, and both versions of noise reduction I believe that I'm certainly entitled to my opinions. There are a lot of us that continually lamented the loss of cda4 and posted frequently to this forum. We are the ones that could have made this product truly the finest mastering program ever written. I wonder how much input was sought from the people who actually use cda.
