The iPad app 'unrealBook' can also do this (MIDI commands to call up Registrations). If anyone here needs help on how to do this, send me a message and I can help out. I have done is successfully and love not having to mess with finding/loading Registrations 'manually' anymore, when using the iPad and the unrealBook app that is . . .
