## What is PistonLink?

PistonLink puts your organ under control. Save and deploy registration profiles across Great, Swell, and Pedal divisions — pushed directly to your organ's memory pistons via MIDI SysEx with a single tap. No more scrambling at the console before the prelude starts.

Registration Profiles. Create a full stop state for your organ and deploy it instantly to any piston memory slot.

Registration Library. Browse curated stop suggestions hymns, verse by verse. Find the right sound and save it straight to any profile — ready for Sunday.

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.

MIDI SysEx 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 the Voice Palette voices from the app, rather than fumbling through the organ menu one at a time.

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.
