I found reference to this IOS app on PSRTutorials and wondered if anyone has used it. It apparently provides access to Registrations for CVP600 series, S750 and S950 and Tyros 5 which are downloaded to your iPhone / iPad then you can send the registration to your keyboard.
It's a free app and you need to log on with FaceBook credentials to comment and do other things with the regs.
Best,
Vince
