Once your payment is complete, your license key will be displayed immediately on the checkout confirmation page and will also be included in your receipt email.

The current Windows version is distributed prior to applying a developer code-signing certificate (unsigned), so some browsers may display additional verification messages or security warnings during download. (The macOS version is already developer-signed and can be downloaded and installed normally without warnings.) In particular, Google Chrome may temporarily restrict newly released installers or display messages such as “Suspicious download.” This warning does not mean that a virus has been detected. It is a conservative notice shown by the browser when a newly released installer does not yet have a Windows developer signature. Continue downloading in Chrome 1. Open the Downloads list. 1. Locate the file showing a warning or being blocked. 1. Click “Keep” or “Download anyway.” Installers downloaded directly from the official quietformat website are virus-free, completely safe, and legitimate files. You can also find many user-created review and demo videos of quietformat plugins on YouTube if you would like additional reassurance before using them. Windows code signing is planned for Q2–Q3 2026. The macOS version is already developer-signed.

That message is prompting you to install the GILLA ARP sound source file (.hr1). (File name: MELTONE_1_0_0_Samples.hr1) To ensure GILLA ARP works properly inside MELTONE, you’ll need to install this file manually the first time you run the plugin. Please check the installation guide included in the MELTONE_Installer(MAC).zip file. (If you’re on Windows, open the folder extracted from MELTONE_Installer(WIN).zip and follow the guide there.) The guide will walk you through all the steps required for the initial setup, including how to install the sound source file.

macOS builds include both VST3 and AU formats, whereas Windows builds include only VST3. In addition, quietformat’s macOS plugin binaries use the Universal Binary format, which means both Intel and Apple Silicon code are contained in a single file. As a result, the file size is larger compared to Windows VST3-only builds.

All quietformat products support the following formats and systems: - macOS 10.13 or later - Windows 10 or later - Plugin Formats: VST3 / AU Compatible with most major DAWs, including Logic Pro, Ableton Live, FL Studio, Cubase, Studio One, and more.
