MuseScore 4.0
MuseScore is music composition and notation software, currently
available from Fedora in the mscore package. Version 4.0 was just
released. If anybody would like to try it out, it is available from
this COPR: https://copr.fedorainfracloud.org/coprs/jjames/MuseScore4/.
I do not intend to build for Fedora until some issues have been worked
out.
WARNING! WARNING! WARNING!
DO NOT TRY THIS IN A WAYLAND SESSION. It will run for anywhere from a
few seconds to a few minutes, then abruptly exit with a "Protocol
error". Run an X session to try MuseScore 4.0.
WARNING! WARNING! WARNING!
WARNING! WARNING! WARNING!
Configuration for MuseScore 3.x and 4.x differs in some important
respects. You may have to do a "factory reset" when switching
versions. Run "mscore -R" or "mscore -F" if it won't start.
This
will clear out your list of recently opened scores, for example, so
backup your configuration before you do this.
WARNING! WARNING! WARNING!
To try it out, run:
sudo dnf copr enable jjames/MuseScore4
sudo dnf install musescore
Please try the video export option, which has bitrotted upstream. I
have attempted to update it for current ffmpeg. Please let me know if
it does or does not work for you. If it works well, I will submit my
patch upstream. Do this: "mscore --score-video <path_to_score> -o
filename.mp4", and optionally try the --resolution and --fps
arguments. Run "mscore --help" for more information. This
functionality does not seem to be available via the GUI.
Upstream bundles fluidsynth, apparently for the sole purpose of
implementing a caching soundfont loader that uses internal fluidsynth
APIs. I have unbundled fluidsynth for this repository, which means
there is no soundfont cache. If you switch soundfonts frequently,
please let me know if the performance is acceptable. If you are
familiar with the fluidsynth API and can implement a caching soundfont
loader using only public APIs, please do so and submit it upstream.
Several other products are bundled (beatroot-vamp, dtl, intervaltree,
rtf2html, and KDDockWidgets). Each of them has either been altered by
the MuseScore developers or, in the case of KDDockWidgets, internal
APIs are used so extensively that I cannot see how to unbundle
successfully. Thoughts on how any of these products might be
unbundled are welcome.
The COPR version makes a long-requested change: the package name
changes from mscore to musescore. Let me know if you encounter any
problems arising from that change.
A new font package is needed to build version 4.0 for Fedora. I would
appreciate a review from anybody who feels competent to review a font
package: https://bugzilla.redhat.com/show_bug.cgi?id=2152347. There
is a question about the appropriate foundry name. If you can help
answer that question, please chime in.
