In the old version I could save the files as midifiles.
How do I do that in Version 2?
It's done a little differently in version 2. Under the File menu, choose Export. You will have your choice of types of midi files or nwctxt.
To read in a midi file, choose Import in the same menu.
I only have the trial version and it seems that you can“t export files then, or?
In the old version it worked it fine.
