We recorded all of our band songs using Windows/Samplitude back in the 2000s. Is there a way to open those files using a Mac so we can save them in a different format? ( I no longer have access to Windows computers )
On each song, I can see different formats, such as .hdp .VIP and .h0
Samplitude is a Windows-only app and those file extensions you list are Magix-specific. Hence, I suspect there is no way for you to access them on a Mac, sorry.
Do you have a friend with a Windows computer who would be prepared to install a recent version of Samplitude and so allow you to at least access your old recordings?
