as far as I know the only method is:
- add markers at each track ID in CD-Architect (since Sound Forge doesnt recognize IDs in a .wav-file)
- export (save) CD-Architect-Project as .wav-File
- open .wav-file in Sound Forge
- convert markers to regions
- extract regions to single-wav-files
- import single-wav-files in DDP supporting 3rd Party application
- create DDP in 3rd Party application
Well, it works but for a professional product like CD-Architect, DDP support (export) really would be "the icing on the cake". :)
Especially in times where upload speeds are high enough to transter masters digitally to the plant.
This decreaces shipping costs und reduces the possibility of errors on Master-CDs.
