Re: Chromatic staff

[Mats Bengtsson]

Getting a 4 line staff is trivial, just add
\override Staff.StaffSymbol #'line-count = #4
at the beginning of your stave. You can also make this setting apply to
all Staff contexts, see the documentation.

For the vertical position, one idea would be to implement a music 
function in
Scheme that modifies the pitch of each note so it gets the pitch it 
would have
if we read the chromatic notation as if it would have been standard 
notation.
The main disadvantage of this solution is that the MIDI output gets 
completely
wrong, otherwise I think it's the easiest solution.
