Modern Cubase can’t open old Cubase .all and .arr project files. I built (with AI) a tool that converts them in batches, so I can get my 30+ year old projects into a modern DAW.
Since Steinberg moved on from Cubase SX/SL, no newer version of Cubase can open or import old Cubase VST (.all) or Cubase Audio (.arr) projects. Some of mine go back to Cubase Audio on the Mac in 1993. The usual workaround is to keep an old PC with Cubase SX or SL just to open the files and re-save them as .cpr. It works, but it’s slow and clumsy, and it’s no help if you never converted your projects back in the day.
The AI is only how I built it. The point is that in 2026 you can automate a job like this, even for file formats nobody supports anymore.
Note: the tool is for personal use. I’m not sharing or selling it, and this isn’t a step-by-step tutorial. I’m showing how I solved my own problem, so hopefully it inspires you to solve yours.
