Barenreiter Verlag used Toppan Scan-Note Software

[Bruce McIntyre]

According to

http://www.npcimaging.com/thesis/Chap2.html 

Barenreiter Verlag used Toppan Scan Note music software. 

Apparently input required the use of three keyboards: Organ, QWERTY,
and a dedicated symbol palette.

A tweaked example of it's output can be found below

and more info here:

it seems pretty primitive to me; tweaking in Illustrator 
seems to be a requirement for a complete score.

Cheers,
Bruce.
