Only thing I have at the moment is Cubase 4...well Cubase is all I've ever used. If I create a project in Cubase. Can the .cpr project format be opened with other software such as ProTools or Adobe Audtion? Seems like it should work...but you never know. Companies don't want their secrets out. It should be like the image extensions. .jpeg, .gif .png. ALL or most photo editing programs can and will open these. session Project files should be portable too.
