Install, step by step.

From download to the first sound in about five minutes. Every plugin runs fully for 7 days, so you can install first and buy later.

Before you start

  • macOS: macOS 11 Big Sur or later, Apple silicon and Intel. Formats: AU (Logic, GarageBand, also Ableton Live and FL Studio) and VST3 (Ableton Live, FL Studio, Cubase, Studio One, Reaper, Bitwig).
  • Windows: Windows 10 or 11, 64-bit. Format: VST3.
  • Pro Tools needs AAX, which is coming. Until then, Kelvinmoor plugins do not load in Pro Tools.
  • Close your music software before installing, so it finds the new plugins when it starts.

macOS: run the installer

  1. Download the installer from the downloads page: one .pkg for all twenty plugins (Kelvinmoor-Complete-…-macOS.pkg) or one per plugin.
  2. Double-click the .pkg in your Downloads folder. If macOS says it can't verify the installer, see the next section.
  3. Click Continue until Installation Type. Leave Audio Units and VST3 both on, unless your software uses only one of them.
  4. Click Install and type your Mac's password when macOS asks for it. That is the password you use to log in to your Mac, not a Kelvinmoor password.
  5. When it says The installation was successful, click Close. You can move the installer to the Trash.

Where the files go: /Library/Audio/Plug-Ins/Components for AU and /Library/Audio/Plug-Ins/VST3 for VST3. Every music app on the Mac looks in those two folders.

macOS: “can’t be verified”

While our installers are waiting for Apple's notarization, macOS may stop the installer with a message such as “Apple could not verify ‘Kelvinmoor-….pkg’ is free of malware”. The installer is safe; macOS shows this for any installer that has not been notarized yet. To open it:

  1. Click Done on the message (not Move to Trash).
  2. Open System Settings → Privacy & Security and scroll down to Security.
  3. Next to “Kelvinmoor-….pkg was blocked to protect your Mac”, click Open Anyway, then enter your Mac's password.
  4. Click Open in the last prompt. The installer starts; continue from step 3 above.

On macOS 14 Sonoma and earlier there is a shorter way: Control-click (or right-click) the .pkg, choose Open, then Open again.

Only do this for installers you downloaded from kelvinmoor.com.

Windows: install the VST3

  1. Download the Windows installer from the downloads page and run it.
  2. If Windows shows Windows protected your PC, click More info, then Run anyway. It appears for new installers until Windows has seen them enough times.
  3. Accept the default folder, C:\Program Files\Common Files\VST3. It is the standard VST3 folder, and every host scans it.
  4. If you got a .zip instead of an installer: unzip it and copy each Kelvinmoor ….vst3 folder into C:\Program Files\Common Files\VST3 (Windows asks for administrator permission).

Find the plugins in your DAW

After installing, open your music software. Most hosts find new plugins by themselves; if not, a rescan does it. Kelvinmoor plugins are listed under the manufacturer Kelvinmoor, with the name and its job, for example KO-2A Opto Comp or SOLSTICE Vocal.

Logic Pro (Mac)

  1. Open Logic. The first time, it checks the new Audio Units by itself; wait until it finishes.
  2. On a channel strip, click an empty Audio FX slot → Audio Units → Kelvinmoor.
  3. Not there? Logic Pro → Settings → Plug-in Manager, select Kelvinmoor on the left, then Reset & Rescan Selection.

  2. Turn on Use VST3 Plug-in System Folders, and on a Mac also Use Audio Units.
  3. Click Rescan. Hold Option (Mac) or Alt (Windows) while you click it for a full rescan.
  4. In the Browser, open Plug-Ins → Kelvinmoor and drag a plugin onto a track.

  3. When the scan ends, click the star next to each Kelvinmoor plugin you want at hand. Starred plugins appear in the browser under Plugin database → Effects.
  4. In the Mixer, click an empty slot on an insert and pick the plugin.

Pro Tools

Pro Tools only loads AAX plugins. AAX versions are coming; we will announce them on the downloads page.

Other hosts

  • GarageBand: AU, under Plug-ins → Audio Units → Kelvinmoor.
  • Cubase / Nuendo: VST3 only. Studio → VST Plug-in Manager → rescan if needed.
  • Studio One: Options (Settings on Mac) → Locations → VST Plug-ins → Reset Blocklist, then restart.
  • Reaper: Options → Settings → Plug-ins → VST → Re-scan.
  • Bitwig Studio: Settings → Locations: the system VST3 folder is scanned by default.

Activate your serial

Every plugin runs fully for 7 days without a serial. When you buy, you get one serial per plugin by email right after checkout (Complete comes with a single serial for all twenty).

  1. Find the purchase email and copy the serial for the plugin. Serials look like KM01-7Q2D-K9FX-30MB: the first part is the plugin's code (KM01 is KO-2A; KMAL is Complete).
  2. Open the plugin in your DAW and click TRIAL in its top bar. After the trial it says ACTIVATE. You can also open the settings menu → Activate license…
  3. Paste the serial into the field and click Activate. The plugin needs an internet connection for a few seconds.
  4. When it says Activated. Thank you!, you're done. Every copy of that plugin on this computer, in any project and any host, is now activated.

Click TRIAL (or ACTIVATE) in the plugin's top bar, paste the serial, click Activate. · illustration

Each serial is active on 1 computer at a time. After activation the plugin works offline for up to 45 days between checks.

Move to a new computer

  1. On the old computer, open the plugin and click ACTIVATE in the top bar (or the settings menu → Activate license…).
  2. Click Deactivate this computer. The serial is free again.
  3. On the new computer, install the plugin and activate the same serial.

The old computer is gone, stolen or broken? Write to support@kelvinmoor.com from your order email and we free the serial for you.

Uninstall

  • macOS: delete the plugin from /Library/Audio/Plug-Ins/Components and /Library/Audio/Plug-Ins/VST3. Deactivate it first if you want to use the serial on another computer.
  • Windows: delete its .vst3 folder from C:\Program Files\Common Files\VST3.
