PolyKB III player

PolyKB III Player is a VST3 plugin component, not a standalone app, so it does not update independently. To get a native Apple Silicon build, you must update XILS-lab itself to a version that ships native VST3 plugins. Visit XILS-lab's website or use their application installer to download and install the latest version of XILS-lab — that will deliver the current plugin builds. If XILS-lab itself does not yet offer native Apple Silicon VST3 versions, contact the vendor directly to ask whether they plan to ship native builds before macOS 28 removes Rosetta 2 support in late 2027. In the meantime, the Intel-only VST3 will continue to load and run under Rosetta 2 on your M-series Mac, but you will need that update path to ensure the plugin continues to work once Rosetta is no longer available.
