I have built the entire LinuxSampler-suite and sfizz (latest versions) for three Fedora releases (41 - 43). They are publicly available on COPR.
https://copr.fedorainfracloud.org/ You can either download the packages or easier, install them via dnf. Instructions are included in the following links.
Release RPMs updated on Copr for new versions (libgig-v4.5.2 and linuxsampler-v2.4.2). Gigedit has not yet been successfully built for Copr but the previous version should continue to work until I get the issue worked out for Gigedit v1.2.4. To reiterate these are only for Fedora 41-43.
To update your installed version, simply type #dnf update and they should update automatically (but only if you have added the linuxsampler-suite repository per instructions in the first post).
