Moving between versions

ASC files created in earlier version of Cobalt or Congo can be opened on Cobalt v8+ using the normal File > Open menu. Subsequent Save or Save As actions will create a new CSF file, which will be used going forward.

Cobalt V8+ can export ASC files by going to File > Export ASCII Light Cues to USB - note that a USB stick is required even on the ETCnomad (offline editor) version. This ASC file can be opened by earlier versions of Cobalt/Congo (though this is not guaranteed, and v8-specific information may be lost), or imported into other consoles
