Here's a feature I don't think ANY workstation software has
Mastering houses and archivists face a very serious problem (and have since the days of tape): that of projects that have little or incorrect information accompanying them in the box.
Projects that go from one studio to another for different aspects (i.e. tracking, mixing, mastering, etc.) NEED to have track sheets, technical info such as sampling rate, bit depth, "Where is Zero?", spatial layouts, names of producers, engineers, assistants, tracking studios, mixing studios, contact names/numbers etc.
There is a lot of other info that should be included with a project as well. I belive that SPARS and the MP&E wing of NARAS have already come up with conventions and a listing of neccessary info that should be included with projects.
Maybe the Ardour project could include a text editor with a print function that would have track sheets,a bunch of the stuff listed above and more. The ability to import fonts would be nice or at least to have a selection of 25 or so public domain fonts. The ability to import a studios' logo and the bands logo as well would be nice. That way the project box holding the masters (or hard drive, CD, or whatever archive media)could have the date, studio/band logo, project name, producer name, engineer name, track tiles, whether it is tracks, rough mixes, final mixes, stereo, 5.1, mono etc. etc.
How about the ability to save and/or print the signal flow of a given track(s), along with the settings of each plug-in inserted on that track?
I don't know of any other DAW software that has this function built into it. One of the things that will make the Ardour project really gain traction is to include features that other products don't have.
