MuseSampler Library not found

• Jul 11, 2025 - 23:17

Okay, I know several people have posted about this, but I wanted to describe my exact situation and what I've done so far. I haven't opened up MuseScore since May, and I decided to make a new score today. When I created the new score, I found that my Muse Sounds were missing from the Mixer even though they are shown as installed in Muse Hub. I did some research and read that I should check Diagnostcs > Sampler, and it says "Muse Sampler Library not found." After more forum crawling, I searched my Windows/System32 and Musescore4/bin folders for the DLL and did not find it. I downloaded it from a trustworthy forum post and installed it in the bin folder, restarted my PC, and reopened Musescore. No change. I then copied it to System32, restarted, and reopened musescore. No change. Can anyone give me any other advice? It seems like this issue has been happening to people since ver. 4.4, but it only just started happening to me in 4.5.2. Am I just not allowed to use one of the main features of Musescore 4's great new playback system until someone gets around to fixing this bug?

I have had this exact same issue as of the same day this was posted, I tried what many people who ran into similar problems did to fix it and havent had success. I restarted my computer, I quit and restarted both musecore and muse hub, I attempted to diagnostic it and was met with muse sampler not found. All of my muse sounds such as muse woodwinds and muse percussion still remain inside of my musehub account but do not show up in the drop down menu in mixer. Previous to me restarting musehub the musesounds option on the home page of musecore 4 did not show anything saying there was no connection but now it shows all muse sounds available for me to download even though they already have been. The files for these sounds are still in my computer AGAIN after redownloading yet musecore 4 wont recognize them in mixer. Even tried manually entering them like one forum suggested in the folders section under preferences and that also led to no success. Looking for someone who can explain why this is even happening atp
