[Linuxsampler-devel] 2.4.0 and 2.3.1 Releases not working on MacOS

[TJ L. <tjl...@ma...>]

Has anyone tested Linuxsampler with a recent version of MacOS? I cannot get LinuxSampler working at all. Obviously, it’s not apple silicon but there are several issues preventing LinuxSampler from working it seems.

- When loading the VST plugin, it is trying to open Fantasia as it does on Windows. However, Fantasia is using a very old version of Java that cannot run in MacOS so Fantasia cannot open. There used to be a workaround to use an older version of JavaApplicationStub, however the version used for Fantasia seems to be deprecated on recent versions of MacOS.



- The AU plugin does not load at all. This includes versions previous to 2.4.0 as well as the most recent 2.4.0 release.



- Both the VST and AU plugins do not scan correctly in several hosts. For example, the VST scans correctly in Reaper but not the AU. In Plogue Bidule, neither the VST or AU scan. In MainStage/Logic (AU support only) the AU does not scan.

- QSampler requires libgig.10.dylib even though libgig.11.dylib was installed for previous versions (2.3.1)  and libgig.12.dylib for the most recent version (2.4.0). So in order to open QSampler, you have to symlink the libgig file and rename it to libgig.10.dylib.



- Even when symlinking to the the old libgig dylib and QSampler opens and the server starts, it does not seem to be able to communicate with the VST plugin at all. The AU plugin does not load on any tested DAW/Host so I cannot test QSampler with the AU. Also, versions previous to 2.4.0 I could at least load an instrument in QSampler even though it could not communicate with the plugin. However, with the latest 2.4.0 version, loading any GIG library crashes QSampler instantly. Obviously, Fantasia would be the better choice but without updated support for newer versions of Java that does not seem possible at the moment.

This is tested on MacOS Sequoia 15.5 on a Mac Mini M4 Pro. I’ve used LinuxSampler quite a bit on both Windows and Linux. I used to use it on Mac pretty extensively in the OSX days before MacOS but not since.

If anyone could take a look it would be much appreciated. Again, this is not an apple silicon compatibility issue. I’m running a few other MacOS intel plugins in Rosetta without issue. Prior to these latest tests, I manually uninstalled all the Linuxsampler package files and then had pgkutil forget the packages before reinstalling the latest version. Please let me know if I can provide any further information.

Much thanks,
