About the VST3 host DAW

The plug-in includes a built-in synth, so it can produce sound on its own even when loaded inside a DAW. To use the built-in synth, turn on the “On” button in the header.

You can also route the generated MIDI to another instrument in your DAW. This requires a DAW that can route the MIDI output of a VSTi to another instrument track.

Verified host: Cubase (Windows and macOS).

Other DAWs (Studio One, Reaper, Ableton Live, and so on) have not been verified. Some DAWs do not support routing a VSTi’s MIDI output, or use a different procedure.

Install as a VST3 plug-in

Windows

Copy the MewMMLPad.vst3 folder to:

C:\Program Files\Common Files\VST3\

Then rescan plug-ins in your DAW. It is recognized as a MIDI-output plug-in (instrument).

macOS (recommended: use install_mac.sh)

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 MewMMLPad.vst3 to:

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

You can open ~/Library from Finder’s “Go” menu → “Library”. After copying, follow the “About the Gatekeeper warning” section below to remove the quarantine attribute.

Install as a standalone application

Windows

Place MewMMLPad.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” (the binary is unsigned).

An audio device settings dialog appears the first time you launch. Select your audio interface. If an ASIO driver is available, choosing ASIO gives lower latency.

macOS (recommended: use install_mac.sh)

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)

MewMMLPad uses ad-hoc signing only and is not notarized by Apple Developer, so macOS Gatekeeper may block it.

If you installed manually without install_mac.sh, run the following in Terminal to remove the quarantine attribute:

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

For standalone use only, you can also launch it via one of the following methods.

Method 1 (right-click to open)

1. In Finder, right-click MewMMLPad.app (or Control-click).
2. Choose “Open” from the menu.
3. When “The developer cannot be verified. Are you sure you want to open it?” appears, click “Open”.

Method 2 (allow from System Settings)

1. Open “System Settings” → “Privacy & Security”.
2. Click “Open Anyway” in the message that appears at the bottom of the screen.

Uninstall

Settings files

Synth presets are stored at:
