Sample Manager looks OK & I like Audiofile Engineering but unfortunately it doesn't seem to know what to do with Sound Designer II disk images. I've got EII disk images that I would like to use - I guess the only thing to do is to use DPX tools in order to write them to floppies for usage in an Oberheim DPX 1.
Pro Tools 12 apparently no longer supports SD2. Kind of crazy, since Digidesign invented the format. But the most surprising thing is that Logic Pro X does! I'm converting my old Samplecell files using logic, and it's very smooth.
