Hi Sailor !
No I did not invent the system, I normally take an ABC file which I my lready have or one which I have taken from a scan of an Old Book AND THEN ENTER IT AS abc.
in this case I used an existing ABC file, exported it as a midi file and then used Notation Composer to make the original dots. Then I altered the setup to make easy notes
you can make as large or small as required.
The reason for showing the naturals was an oversight by me, "not proof reading correctly" but the software just put them in. My apologies. I have produced some stuff for a teacher
who uses it I believe for teaching simple melodies to primary/junior pupils to music on the recorder.
Hope this helps any assistance I can give you please ask.
Regards
Voyager
