-- I would like to avoid that ties across line breaks run _through_ the
-clef on the new line
-
-- I would like the possibility of forcing clef- and key- changes to be
-printed _after_ the new bar line
-
-- I would like an option to define the number of systems on which the
-score must be distributed. As it is now it seems that I may only
-influence that indirectly through the gourlay_maxmeasures property.
-
- if I change the property minVerticalAlign in a multi staff score with
lyrics the change affects the lyrics too. I would like the change to
_only_ affect staves.
- I would like to be able to influence the sloping of xtuplet brackets
-- for one of my test scores containing a modern edition of an early
-17'th century composition I have a leading measure containing the
-orginal clefs and note values of the original composition. I use the
-"harmonic" and "diamond" note head styles for that measure and would
-like to have the stems of these notes _centered_ on the notehead as in
-the mensural music notation.
-
- after the leading measure in the above mentioned score I want a double
bar line fully drawn across the staves and after that keep to the
ChoirStaff bar line types in the rest of the scores
+. * Write script that uses --find-old-relative to do auto relativization.
-- I would like to be able to define invisible melismatic slurs in order
-to avoid printing slurs conflicting with an original ms of printing. Of
-course I can achieve that by just inserting empty syllables in the
-lyrics. But this facility implemented in the MusiXTeX preprocessor M-tx
-is nice so ...
-
-- if I explicitly beam notes in a staff with auto beaming disabled I
-would like to have these beams also to be melismatic.
-
-- do I need to get warnings on 'No one to print a repeat brace' when I
-issue a '\repeat fold 2 \alternative' statement with an empty leading
-text item in a \lyrics context in order to achieve multiple lyrics lines
-in a _section_ of a score ?

-> 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.
