Thanks, Ivan, for your help. "G" for time, now why didn't I think of that?I am getting closer to my goal. This morning I couldn't sleep, so I experimented with the Record function in EZPiano. (It's not mentioned once in the manual, so I've been ignoring it all these years.) Anyway, I got EZPiano to make a MIDI file, and I got NoteWorthy to open it.
Now I can't seem to save it to NoteWorthy, because NW refuses to admit that itself exists. (It doesn't list itself as being one of my Program Files.) But I'll think of something.
