MuseSampler is not recognized by Fedora rpm It recognizes the Musescore appimage file: ---------------------------------- $ mscore [...] [1;31m09:46:55.288 | ERROR | main_thread | MuseSamplerLibHandler::init | Could not init lib[0m [1;31m09:46:55.288 | ERROR | main_thread | MuseSamplerResolver::init | Could not init MuseSampler: /home/gland/.local/share/MuseSampler/lib/libMuseSamplerCoreLib.so, version: 0.102.2[0m ----------------------------------- ----------------------------------- $ MuseScore-Studio-4.6.2.252830930-x86_64.appimage [...] [1;32m11:25:09.055 | INFO | main_thread | MuseSamplerResolver::init | MuseSampler successfully inited: /home/gland/.local/share/MuseSampler/lib/libMuseSamplerCoreLib.so, version: 0.102.2[0m Reproducible: Always Actual Results: You cannot use your MuseSampler bank.
Which version of musescore do you have installed? rpm -q musescore
Sorry, I should have specified that: 4.6.2, as for the appimage. # rpm -q musescore musescore-4.6.2-27.fc43.x86_64 Thank you
No problem. I figured that was what you probably had, but thought I should check. This is really disappointing. I have been eagerly awaiting the 4.6 series to get the Qt fixes we need to finally move beyond 4.3.2. I didn't think to check that Muse Sounds worked. And I'm really sorry to tell you this, but I am at a conference all this week. I'm probably not going to have time to debug this issue until next week. I'll try to find some time during an evening, but I can't promise anything.
Thank you very much. I'm using the appimage in the meantime.
This does not seem to be an issue I can debug, since it involves code inside the MuseSampler library. I have opened an upstream issue to ask them to investigate.
Thank you, we'll wait for their response.
Sorry for taking so long. For me, the fix was to do a factory reset. MuseSampler must be confused by something in the config files written by a previous version of MuseScore. Start MuseScore, then select the Help menu. The last item on that menu is "Revert to factory settings". This will erase any customizations you have made and erase your list of recent scores, unfortunately. But it does make MuseSampler work again. Also, if anyone is interested, version 4.6.3 is now in testing: https://bodhi.fedoraproject.org/updates/FEDORA-2025-995baf50af. This build also enables VST support.
Thank you very much, it works. Sorry, I didn't think to restore the original configuration, which would have saved you some work. I downloaded version 4.6.3 and everything is working fine for now. Thanks again. Gérard
Apologies for bumping this issue, but I've only now decided to try and give MuseScore a chance on my Fedora 43 (so far, for various reasons, I was sticking to MuseScore 3 with old rpms). I'm getting the "Could not init" error too, but unlike you, reverting to factory settings didn't fix it for me. This is using MuseScore 4.6.5 from the Fedora repos, and the latest Muse Sounds Manager rpm (2.1.1.912) from MuseScore's downloads.
Well ... doggone. I'm seeing it again now, too. The problem is that Muse Sounds Manager is a black box. I can't debug what happens inside it. If its init function decides to return an error, I have no way of telling what it thinks is wrong. I'll try a few things and see if I can figure out how to make it happy again.
