Fw: définition d'un nouveau cont exte

[Germain G. Ivanoff-Trinadtzaty]



Hello,

 

I've got two problems defining a new context \StaffSA, based on \Staff.

I followed instruction from NR 6.2.5 Defining new contexts.

http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Defining-new-contexts#Defining-new-contexts

 

With the definitions that follow :

1) I get two staves for one  \new \StaffSA

2) their instrumentName don't print

 

What's wrong ?

 

Thanks,

Germain

 

ps: btw, are de sharps (#) well suited ? (i mean : in the right place ?)
