Re: new key signatures

[Mark Dewey]

Thanks for the information!  I have another related 
question, now, though.

I've found that the following code will get the key 
signature to look right:
\new Staff
{
	\set Staff.keySignature = #'( ((1 . 4) . 2)   ((1 . 
1) . 2)  )
        b4 c' dis' e' f' gis' a' b'
        c'' dis'' e'' f'' gis'' a'' b''
}

However, when I define a key signature, the 
sharps/flats don't apply for the note
in every octave--just the octave I specify.  Is there a 
way to make it apply to all
octaves without having loads of symbols on the key 
signature?
Notice that in the above code the key signature only 
seems to apply to dis'' and gis'',
and not dis' and gis'.

Here's a definition of how this seems to work:
\set Staff.keySignature = #'( ( (a . b)  c) )
a = Octave
b = Vertical position / Note value
c values:
        1: half sharp
        2: sharp
        -1: half flat
        -2: flat
Where a = 1
        if b = 2, the note is e''
        if b = 1, the note is d''
        if b = 0, the note is c'', etc.

I'm wondering if perhaps there's a value for 'a' that 
will cover all octaves, and put the
sharp/flat symbols in the regular octave-positions.
