GOD KEY MASTERING plug-in

Install guide

Get GOD KEY MASTERING running in Logic Pro, GarageBand, MainStage and any DAW that uses VST3 plug-ins. Needs macOS 11 or later, on Apple Silicon or Intel.

About the security warning

GOD KEY MASTERING isn’t signed through Apple’s paid developer program yet, so the first time you open it macOS says it “can’t verify the developer”. That’s expected. You approve it once, as shown below, and macOS remembers.

Which download is which

Installer (.pkg)Recommended. Audio Unit, VST3 and the standalone app in one step. You can untick parts you don’t want.
Logic Pro & GarageBand (AU) .zipJust the Audio Unit, for Logic Pro, GarageBand and MainStage.
Other DAWs (VST3) .zipJust the VST3, for Ableton Live, FL Studio, REAPER, Studio One, Cubase, Bitwig and others.

Your downloads are in The Vault once you’ve bought the plug-in.

1. Run the installer

  1. Double-click GOD KEY MASTERING Installer.pkg.
  2. macOS shows a warning. Click Done (or OK). Don’t move it to the Bin.
  3. Open System Settings › Privacy & Security. Scroll down to Security, where it says the installer was blocked, and click Open Anyway. Enter your Mac password, then click Open.
  4. Follow the installer. Choose Install for me only unless other people on this Mac need it too.

On macOS 14 Sonoma and earlier you can skip step 3: Control-click (or right-click) the installer, choose Open, then click Open again.

Or install from a .zip

  1. Double-click the .zip to unpack it.
  2. Control-click (or right-click) Install.command, choose Open, then Open again. On macOS 15 Sequoia and later, if there’s no Open button: click Done, then Open Anyway in System Settings › Privacy & Security.
  3. A Terminal window says Done when it’s installed. Press any key to close it.

Prefer to do it by hand? Drag the plug-in into ~/Library/Audio/Plug-Ins/Components (Audio Unit) or ~/Library/Audio/Plug-Ins/VST3 (VST3), using Finder’s Go › Go to Folder. Then run this in Terminal so your DAW can load it (shown for the Audio Unit):

xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/Components/"GOD KEY MASTERING.component"

2. Logic Pro

  1. Open Logic Pro. It checks new plug-ins as it starts.
  2. Show the Mixer (X). On the Stereo Out channel, click an empty Audio FX slot.
  3. Choose Audio Units › Rebel G Society › GOD KEY MASTERING. Put it last on Stereo Out.

Not in the list? Go to Logic Pro › Settings › Plug-in Manager, select Rebel G Society and click Reset & Rescan Selection. If it’s still missing, restart your Mac once. For mastering, turn Low Latency Mode off and set Settings › Audio › General › Plug-in Latency Compensation to All.

3. GarageBand

  1. Go to GarageBand › Settings › Audio/MIDI and turn on Enable Audio Units.
  2. Choose Track › Show Master Track and select the master track.
  3. Open Smart Controls (B), show the Plug-ins area, click an empty slot and choose Audio Units › Rebel G Society › GOD KEY MASTERING.

If your GarageBand doesn’t show plug-in slots on the master track, export your mix, import it on a new audio track and put GOD KEY MASTERING on that track.

4. Other DAWs (VST3)

Most DAWs find new VST3 plug-ins on their own. If yours doesn’t, rescan. Menu names vary a little between versions.

Ableton LiveSettings › Plug-ins: turn on Use VST3 Plug-in System Folders, then Rescan
FL StudioOptions › Manage plugins › Find plugins
REAPERSettings › Plug-ins › VST › Re-scan
Studio OneSettings › Locations › VST Plug-ins, then restart Studio One
Cubase / NuendoStudio › VST Plug-in Manager › Rescan
Bitwig StudioSettings › Locations › Rescan

Put GOD KEY MASTERING on your master (stereo output) channel, after everything else. MainStage works like Logic Pro: Audio Units › Rebel G Society.

5. Activate

  1. Open GOD KEY MASTERING in your DAW and click SETTINGS (top right).
  2. Type or paste your licence key (GKM-…) in the LICENCE box and click ACTIVATE. Your Mac needs to be online for this one step.
  3. It says Licensed to your name or email. Every DAW and the standalone app on this Mac are now activated.

Your key is in your order email and in The Vault. One key works on 2 computers: to move it, click DEACTIVATE on the old one, or contact us. Without a key, GOD KEY MASTERING runs as a full 14-day trial. After that it passes your audio through unprocessed (it never mutes your session) until you activate.

Quick start

  1. In the left panel, pick a profile, a loudness target and an intensity.
  2. Click ANALYZE and play your song, or at least its loudest part.
  3. Click AUTO MASTER (top right). CHANGES shows what it did and why.
  4. Compare with BYPASS and GAIN MATCH. Turn Gain Match off before you bounce.

Troubleshooting

  • “is damaged and can’t be opened”: run the xattr line above for that plug-in, then reopen your DAW.
  • Not in your DAW: rescan plug-ins, then restart your Mac once.
  • Activation fails: check the key against your email (letters O and I are read as 0 and 1, so either works). “Already active on 2 computers”: deactivate an old one or contact us.
  • No sound change at all and the top bar says ACTIVATE: the trial has ended. Activate in SETTINGS.
  • A preset sounds almost silent: a DELTA or SOLO button is on in one of the stages. Turn it off.
  • Uninstall: run bash uninstall.sh from your download. Your presets are kept unless you add --remove-presets.
