Does the maximum size of a stable .cpr exists, if so, which is it ?



Do you mean the file size, or count of tracks, or count of Inserts? It’s always system dependent. In general, there is no limit (with Cubase Pro).

I meant the file size. Thanks Martin!


No. No limit with the File size. In general, the files are not so big. The biggest is the Audio/Video data/files, but these are handled as an external files.
