After completing your purchase, you'll receive an email from Apophenia with your license key - usually within a few minutes (your Paddle payment receipt arrives separately). The download itself is available any time from the plugin's page: it's the full plugin, and your key unlocks it.
Double-click the downloaded Vellum-Setup.exe (or Penumbra-Setup.exe) and follow the steps. If Windows shows a SmartScreen notice, that's expected for new independent software - see the FAQ below.
The plugin is placed automatically in the standard VST3 location recognized by all major DAWs on Windows:
No manual copying needed. Uninstall any time from Windows Settings → Apps.
Open your DAW and trigger a plugin rescan. In most DAWs this is under Preferences → Plugins → Scan / Rescan. After scanning, search for "Vellum" or "Penumbra" in your plugin browser.
Go to Options → Preferences → Plug-ins → VST and add C:\Program Files\Common Files\VST3 to the scan paths if it's not already there. Click "Re-scan". PDC is on by default in Reaper - Vellum latency is compensated automatically.
Go to Preferences → Plug-Ins. Make sure "Use VST3 Plug-In Custom Folder" is enabled. Rescan. Live has PDC and will handle Vellum latency automatically.
Go to Options → Manage plugins → Find more plugins. FL Studio scans C:\Program Files\Common Files\VST3 by default. PDC must be enabled in project settings.
Yes. Windows SmartScreen shows a "not commonly downloaded" warning for new independent software that hasn't built download reputation yet - this is normal for small plugin makers. As long as you downloaded the installer from apophenia.studio, click Keep in the browser, then More info → Run anyway when Windows asks. The warning fades away on its own as more people download the plugins.
Check your spam folder first - the email comes from apophenia.studio and usually arrives within a few minutes of purchase. Note that your Paddle payment receipt is a separate email. Still nothing? Email us at support@apophenia.studio and we'll resend your key.
Check that C:\Program Files\Common Files\VST3\ contains the plugin (the installer places it there), then trigger a full rescan in your DAW - in most DAWs under Preferences → Plug-ins. Some DAWs require restarting after scanning. Still missing? Re-run the installer and rescan.
We offer a 14-day refund window for technical problems we can't fix, products not as described, or accidental duplicate purchases - and we encourage trying the free demo before buying. Email support@apophenia.studio with your order number. See the full Refund Policy.
Yes. Your license covers personal use on up to 5 machines you own (e.g. studio desktop + laptop). Activation is one-time per machine - after that the plugin works fully offline. For more machines, please purchase an additional license.
macOS builds are planned for the future. There is no confirmed release date yet. If you purchase a Windows license today, you'll receive the macOS version at no extra charge when it releases.
