Dial it back, Svenne.
Yes it would be lovely if Steinberg provided the import functionality they used to maintain in earlier versions of Cubase, but that ship sailed with the advent of Cubase 4. They haven’t bothered with any user requests to restore the old import options in 9 years. It stands to reason they never will. So you look for alternatives.
I provided a detailed solution, if the OP happens to be on a Mac that can boot from 10.6.8.
And yes, I maintain one drive loaded with 10.6.8 and older versions of Cubase to deal with a backlog of older ideas/demos/unfinished Projects, many of which use plug-ins that no longer run on C8/10.10.2. I need to open those in the older system/Cubase versions to find out what I used and to figure out substitutions for updating the Projects to C8 in Yosemite and…to occasionally run SX3 for some really old .ALL/.ARR stuff. Works a charm, BTW.
