I hadn't tried this before with Cubase SL (v1.6) and was a bit gob smacked that the application deosn't support this! That is seriously slack programming from Steinberg - even 'Notepad' supports d&d of a text file!!
So...to try out a folder with e.g. 100 little MIDI files in it, each one has to be imported seperately, one-at-a-time...
