ABOUT PISTONLINK PistonLink was built for your organ. Save and deploy registration profiles across Great, Swell, and Pedal divisions, or receive them from the organ into a profile that you can take anywhere with you — directly to your organ's memory pistons via MIDI. No more scrambling at the console before the prelude starts. 18 SUPPORTED ORGAN MODELS - Rodgers 751A, 751B - Rodgers 790C, 790B - Rodgers 795 - Rodgers T788 - Rodgers 835B - Rodgers 905E - Johannus Symphonica 47 - Johannus WM-44 - Johannus WM-47 - Johannus WM-49 - Allen AP-16, AP-22 - Allen LD-34b - Allen MDS-6 - Allen R-270 - Viscount Cantorum Trio Plus - More to come! REGISTRATION PROFILES Create a full stop state for your organ and deploy it instantly to any piston memory slot. IMPORT PRESETS FROM THE ORGAN You can connect to the organ, and dump your stops from various pistons directly into a new profile, so manually transferring is a thing of the past. REGISTRATION LIBRARY Browse curated stop suggestions for hymns, verse by verse. Find the right sound and save it straight to any profile — ready for Sunday. ENCORE Record your registration changes and expression pedal moves in real time, then play them back exactly as performed. Capture a piece once and let PistonLink handle every stop change and swell shift automatically. Only available on supported organ models. HANDS-FREE PAGE TURNS Import any PDF and turn pages without lifting your hands from the keys. Wink right to advance, wink left to go back. Never locked behind an in-app purchase. Features a built-in metronome for ensuring you stay on beat. PISTONLINK COMMUNITY Share your favorite hymn registrations with other PistonLink organists, and download theirs to use on your own organ. Everything you share is reviewed before anyone else can see it, and nothing is shared unless you choose to send it. Downloads are free and work offline, and registrations made for a different organ are translated to yours automatically. ORGAN DETECTION Not sure what organ you have? PistonLink can help you identify what organ you have if you're not sure. MIDI SYSEX AND PROGRAM CHANGE INTEGRATION PistonLink communicates directly with your instrument over MIDI — writing registrations to the organ's own memory with precision. This also includes a shortcut to access Voice Palette voices from the app, rather than fumbling through the organ menu one at a time. CATALOG YOUR ORGAN Is your organ not supported out of the current 16 organs? Use the catalog your organ feature to help get the information needed to the developer to get it usable in the app! AI HYMN REGISTRANT Can't find a hymn in the curated library? Just ask. PistonLink's AI Hymn Registrant uses on-device Apple Intelligence to suggest organ stop registrations for any hymn — instantly, privately, and without an internet connection. Review and adjust every suggestion before deploying it to your organ. Supports the latest in SIRI AI and Apple Intelligence.
