Moin,
I just tried this on S1:
- - create an empty instrument track
- - drag and drop a midi file from desktop on there
- - works fine here.
If you are using the artists' version: Do you have the VST bridge/plugin installed? I think that is a separate buy.
If you are using a version of S1 that has built-in VSTi support: Can you drag and drop ANY instrument (VSTi, not general VST/FX) onto the empty track field to create a new instrument track? Does the VST get loaded then?
