+. * junk separate mudela versioning.
+. * petite-ouverture time sig size.
+. * PostScript
+. * header for PS enteredby = "bla <bla@bar.com>"
+. * ps/lily.ps see comments.
+. * By the way, I'm not sure the translation of 'C, G, and F clef'
+> should include Alto, Violin, Bass <clef translated>.
+[..]
+
+I understand your point. It should be changed.
+
+
+>
+> The terms C-clef, G-clef, F-clef stand for the signs, being
+> mutated forms of a C, a G and an F.
+>
+> The terms Violin Clef etc. stand for the signs being used in
+> special positions on the staff.
+>
+> The G-clef-sign indicates g' on the line around which the
+> snake centers. It is a Violin Clef if it is centered around the
+> second line (from below), and a French Violin Clef if it is
+> centered around the lowest.
+>
+> The C-clef indicates c' on the line that gets
+> 'pinched' by it. It is a Soprano, Mezzosoprano (English?), Alto, Tenor
+> and (don't remember exactly, maybe Baritone) Clef, depending on
+> the line (from highest to lowest).
+>
+> The F-clef-sign indicates f on the line between
+> the two dots. If it's on the second line from above, it is called
+> Bass Clef. If it's on the middle line, it is called (maybe
+> Baritone) Clef too, because it indicates the same pitches as the
+> C-Clef on the highest line. So, you could write an Alto Clef by
+> putting the F-clef sign on the lowest line (but that's _very_
+> uncommon).
+>
+> Sorry, this is written very messy because I'm in a hurry,
+> but I hope you understand what I want to say.

+. * Aha, the problem is the new TeX code generation for changing fonts.
+> (The explanation below is mostly intended for Han-Wen and Jan)
+> Before, the font was changed with macros declared separately for
+> pure TeX and LaTeX, but now all the fonts are declared directly in
+> the generated code using the low-level TeX commands. This circumvents
+> the fontencoding mechanism of LaTeX and is a potential source of
+> problems also for us users of the Latin-1 character set.
+> I think it still works since the inputencoding latin1 is
+> declared by ly2dvi, but it still means that e.g. an o with
+> umlaut is typeset as a combination of the two symbols 'o' and
+> 'umlaut' instead of as a single character, as would be the case
+> if fontencoding OT1 had been used. This shouldn't give any
+> difference in layout, though. One of the main argument for using
+> fontencoding OT1 is for the hyphenation mechanism to work, an
+> argument that's clearly irrelevant in our application. Yet we
+> see the problem for August.

+> Would it be hard to add support for proper dynamics in MIDI output? I
+> would really like to have this feature...
+
+Concretely spoken, for dynamics you have to write a performer
+(Dynamics_performer), that will take the input requests. If I
+understand correctly, every MIDI note played must have its dynamic
+strength set separately. That means the the Dynamics_performer must
+set the strength of every Audio_note it finds. This means that one
+has to modify existing Audio items. The best way of doing this is
+with a broadcast/acknowledge process.
+
+So the best way of handling this, is
+
+ 1 supporting dynamic settings in Audio_note
+
+ 2 Write a Dynamics_performer that will modify
+ any notes it finds to set appropriate strengths.
+
+I'd say that the work involved is not hard, but you have to be fluent
+with C++ and need some insight into the working of Notation Contexts
+and friends. I guess I could do it in a day or so, but if you are not
+so fluent with the inner workings of LilyPond, it could take you some
+more time (A few more days?).
+
+Please note, that I am *not* going to code this myself: my days are
+valuable, and I think I have more interesting things to do than fixing
+the MIDI output (I don't even have a soundcard). But I *do* want to help
+you or other people with implementing this, so if you need help, don't
+hesitate to ask.

+Han-Wen Nienhuys <hanwen@cs.uu.nl> writes:

+> Foo_class *class_ptr_
+> }
+
+Usually you can get away without having this interlinked structure.
+One piece of information you need when exporting objects to scheme is
+the smob tag for your class. You might store this value (a long) into
+a class static variable, or a file static variable. I'll use a class
+static variable in this example.
+
+I typically use code that works like this (untested code ahead):
+
+class Foo_class {
+ static long *Foo_smob_tag;
+ SCM obj; // representation as a scheme object, description comes later
+}
+
+// call this once on startup
+void init_Foo_class {
+ static scm_smobfuns type_rec;
+
+ type_rec.mark = foo_mark;
+ type_rec.free = foo_free;
+ type_rec.print = foo_display;
+ type_rec.equalp = 0;
+ Foo_class::Foo_smob_tag = new int(scm_new_smob(type_rec));
+}
+
+When you want to export an object to scheme, you put a pointer to the
+object itself in the cdr of the cell, and the tag in the car of the
+cell. The code looks like this:
+
+// Is this a Foo?
+static int
+foo_p(SCM obj)
+{
+ return(SCM_NIMP(obj) && SCM_CAR(obj) == Foo_class::Foo_smob_tag);
+}
+
+// given a Scheme representation, return, a C++ representation
+static Foo_class *
+foo_unbox(SCM obj)
+{
+ return((Foo_class*)SCM_CDR(obj));
+}
+
+// the SCM representation of the object is stored inside itself
+// this will become useful when destructor gets called
+static SCM
+foo_box(Foo_class *foo)
+{
+ SCM_DEFER_INTS;
+ SCM_NEWCELL(foo->obj);
+ SCM_SETCAR(foo->obj, Foo_class::Foo_smob_tag);
+ SCM_SETCDR(foo->obj, (SCM)foo);
+ SCM_ALLOW_INTS;
+ return foo->obj;
+}
+
+> C++ determines life time, so what is the strategy?
+
+What happens now when the destructor gets called? Lets set the cdr to
+NULL, and then check for that in all of the primitive functions that
+use your smob. We'll call this notion 'live'; a scheme object is
+'live' if the C++ representation still exists, it's dead if the C++
+object is gone. You can still have references to dead objects in
+scheme code; it's just an error to use them. This idea is stolen from
+Emacs's handling of buffers ('buffer-live-p' and friends).
+
+Add another function, foo_live_p:
+
+static int
+foo_live_p(SCM obj)
+{
+ return(foo_p(obj) && SCM_CDR(obj) != NULL);
+}
+
+In you destructor, you need to do:
+
+~Foo_class()
+{
+ SCM_CDR(this->obj, NULL);
+}
+
+When writing new primitives, now just check foo_live_p().
+
+I hope the above helps,
