Hi… I actually do both at the same time. I have a little router, that I set to “access point“ mode, and I use it to connect multiple iPads on the LAN together at gigs. I use unrealbook app, with my iPad acting as master. Whenever I change to a different song on the iPad, everybody in the band who has an iPad, their iPad changes to that same song.
Separately, at the same time, I use the wireless Midi Device I mentioned, so that the unrealBook iPad app can send midi commands to the Tyros or Genos, for recall of registrations. This way, when I call up a song on my iPad, everybody else’s iPads change automatically, and the keyboard is ready with the registration for that song. Makes life a lot easier and gigs! Especially when taking requests…
I have used both of these together for many dozens of gigs, without any problems.
