PistonLink was built for your organ. 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.
PistonLink currently supports:
- Rodgers 790C, 790B
- Rodgers 751A, 751B
- Rodgers 795
- Rodgers T788
- Rodgers 835B
- Johannus WM-44
- Allen AP-16
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 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.
Organ Detection. Not sure what organ you have? PistonLink can help you identify what organ you have if you're not sure.
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 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.
