MS-20 Authorizer
MS-20 Authorizer is a utility for authorizing and managing the MS-20 synthesizer app from Korg, a software emulation of the classic Korg MS-20 hardware synthesizer. The MS-20 is a semi-modular monophonic synthesizer known for its distinctive sound design capabilities, patch-cord modulation system, and filter characteristics. The Authorizer app handles software licensing and authentication for the MS-20 and related Korg products, ensuring that only licensed copies of the software can run.
AI Recommendation
1 suggestionMS-20 Authorizer is a licensing utility bundled with Korg's MS-20 synthesizer software, not a standalone application — it is a helper component that manages authentication for the main MS-20 app. You cannot update this utility separately. Instead, check whether the MS-20 synthesizer itself has been updated to a native Apple Silicon build by visiting Korg's website or launching your MS-20 app and checking for updates through its preferences or Help menu. If the MS-20 synthesizer is still Intel-only, contact Korg directly to confirm whether a native Apple Silicon build is planned, since an Intel-only build will stop working when Apple removes Rosetta 2 in macOS 28 (late 2027). In the meantime, the authorizer and the MS-20 will continue to run under Rosetta on current macOS releases.
