Opening Old Cubase SL1 files in Cubase Artist (latest version)
If I purchase a 2024 version of Cubase (Artist or Pro)…
… will I be able to convert / work on my hundreds of songs produced in the 2003 version of Cubase SL1 ? (They had .CPR and .CSH file extensions.)
You should be able to open .CPR files from Cubase SL1 directly in Cubase 13 (any edition), but some of the plugins might not be present any more in the current versions. You can also download a trial current Cubase version and test this out yourself before purchasing.
