Getting back on point of the tutorial,
<< I read your comments and you made a fair point - the HOW wasn't obvious, the magic of the software across platforms is "deceptive" >>
'How' was explained step by step in the tutorial... Open midi - import the same midi file... How to do that was explained. Can we discuss your point to what is ambiguous to the instructions of 'how' to open and then import the same midi file?
