Description
Issue type
VST bug
Description with steps to reproduce
- Download a free Linux VST3 FX from Auburn Sounds
- Install it in a folder (I did this by copying the .so file to the VST3-nominated folder; Is this correct?)
- Open MuseScore and in Preferences > Folders > VST3 select the applicable folder and click on Scan then OK.
- Open a file and engage the downloaded Effect in the mixer.
Expected result: The effect can be found and works as advertised.
Actual result: The Effect cannot be found.
There are two issues here:
- VST3 for Linux distros is apparently enabled from MS 4.6 onwards, but no FX can be downloaded from musehub.com.
- Other (non-Musehub) VST3 FX do not seem to work.
In which versions of MuseScore Studio is this issue present?
MuseScore Studio version (64-bit): 4.7.4-260706075, revision: github-musescore-musescore-7688c00
