What's New in P422 Fairuz
3.0.1
October 27, 2026
P422 Fairuz 3.0.1 • Move to folder: touch and hold a preset or a folder in the browser and choose Move to folder... to put it in another folder. A finger on the lists now only scrolls, so nothing moves by accident. • Factory presets you delete, rename or move now stay that way. They no longer come back the next time the app or the plug-in starts. • The browser fits small screens: on an iPhone held upright and in small plug-in windows, the stars, buttons and search field now fit. • In a host app, Manuals copies the link to the Quick Guide or the User Guides. Paste it into your browser to open it. • Smaller fixes and refinements. Requires iOS 15 or later.
