System requirements

Item Details
OS (Windows) Windows 10 / 11 (64-bit)
OS (macOS) macOS 12 or later (Apple Silicon / Intel Universal Binary)
VST3 host Verified on Cubase (Windows / macOS)
Standalone (Win) ASIO-compatible audio interface recommended; WASAPI also works
Standalone (Mac) Core Audio

Verified host: Cubase (Windows and macOS).

Other DAWs (Studio One, Reaper, Ableton Live, and so on) have not been verified. MewFM behaves as a standard VST3 instrument, but the exact procedure can vary by host.

Install as a VST3 plug-in

Windows

Copy the MewFM.vst3 folder to:

C:\Program Files\Common Files\VST3\

Then rescan plug-ins in your DAW.

Unzip the archive and run, in Terminal:

cd <unzipped folder>
./install_mac.sh

This copies the VST3 and clears the Gatekeeper quarantine automatically. After it finishes, rescan plug-ins in your DAW.

macOS (manual install)

Copy MewFM.vst3 to the following folder, then follow the Gatekeeper section below to remove the quarantine attribute:

~/Library/Audio/Plug-Ins/VST3/

Install the bundled presets

The ZIP includes a Presets folder with the factory presets. Installing them makes them appear in MewFM’s preset list.

Windows

Double-click install_presets.bat. It copies the presets to:

Documents\MewFM Presets\

macOS

In Terminal, run:

cd <unzipped folder>
./install_presets.sh

It copies the presets to:

~/Documents/MewFM Presets/

Once installed, you can overwrite, delete, or otherwise edit them as ordinary presets.

Install as a standalone application

Windows

Place MewFM.exe in any folder and double-click to launch. No installer is needed.

If “Windows protected your PC” appears on first launch, click “More info” → “Run anyway”.

An audio device settings dialog appears the first time you launch.

cd <unzipped folder>
./install_mac.sh

This installs both the VST3 and the standalone, and clears the Gatekeeper quarantine automatically.

About the Gatekeeper warning (macOS)

MewFM uses ad-hoc signing only and is not notarized by Apple Developer, so Gatekeeper may block it on first launch.

If you installed manually without install_mac.sh, run the following in Terminal:

xattr -rd com.apple.quarantine \
    ~/Library/Audio/Plug-Ins/VST3/MewFM.vst3
xattr -rd com.apple.quarantine \
    /Applications/MewFM.app

Uninstall

Type Remove
VST3 (Windows) C:\Program Files\Common Files\VST3\MewFM.vst3
VST3 (macOS) ~/Library/Audio/Plug-Ins/VST3/MewFM.vst3
Standalone (Windows) MewFM.exe (delete from wherever you placed it)
Standalone (macOS) /Applications/MewFM.app

Preset files

Windows: Documents\MewFM Presets\
macOS  : ~/Documents/MewFM Presets/

MewFM does not use the Windows registry.
