I know of one Notation programme that uses the first seven letters in each row on the QWERTY keyboard, moving left to right, to represent “C-D-E-F-G-A-B”. There is another one, that “requires” you to know how to type, to the extent, that you have to actually type in the actual letters that correspond to the pitches. I find the first system to be more intuitive.
The second programme allows a degree of “customisation” of the note entry process.
What is/will be Dorico’s approach?
