Hi Éloi

It would be great to have more help with Denemo - there are many
unfinished sub-projects in the code.
I wonder if you would like to copy your email to the mailing list
(address@hidden) as there will be people listening there that have
ideas about what they would like to see progressing in Denemo.
Here are a couple of things that I know of, one fairly simple and one
which is much more open-ended.

1) The preferences dialog is largely not translatable. The code
(prefdialog.c) uses macros to avoid repeating the same code for getting
and setting the preferences. These take a string which is then wrapped
with the function call _() (itself a macro for gettext() IIRC).
For some reason this seems not to work. Either a better understanding,
or running the compile stage with -E to see the pre-processor output is
needed. And some straightforward method of checking that a string will
be translatable (I can't trigger running Denemo with translations
appearing, for some reason).

2) There is the start of code to allow people to transcribe music that
is in audio form (that is: create notation for some music that they have
a recording of). The code allows to open a recording (.ogg format,
perhaps others) and then to synchronise empty measures with the music
(by the user tapping the space bar at the start of each measure as
Denemo plays the audio back). Each measure has its own tempo setting
inserted so that when the notes are inserted into the measures they keep
step with the music. When the score is played the audio is played in
sync.
This works, but only to some extent, discrepancies in timing being
audible. At this stage in the development (as I only had a very old slow
machine) I stopped work and have not got back to it. There is very
little error reporting and the mixing of the audio and the MIDI is done
simply by playing one in the left stereo channel the other in the
right...

One of the things you need to think about is what your personal
interests and preferences are: some people enjoy tidying up - I have
started towards making Denemo compile with -Wall, some files now pass
that without warnings. And view.c is a horror story of multiple topics
all stuffed into one file, it needs splitting into at least three.
Others would be more interested in making the MIDI playback follow more
of the indication in the score...
I'll try and put these and other ideas onto the website.

Best wishes

Richard
