If you use Songbook+ for your sheet music, you can also hook up your Genos to your Ipad with WIFI and not need an adaptor. Then you can have your keyboard control your sheet music and your sheet music control your keyboard. For an example. when you click on a registration, the corresponding sheet music, will cue up, and vice versa, if you click on a sheet music the corresponding registration will be selected on the keyboard.
I just set this up on my Genos yesterday, with some help from Fred Smith's video and others who have done this since Genos came out, and it is a real nice feature, if you have 1700 pieces of sheet music as I do.
As stated above, it's for loading Expansion Packs as well.
Well worth configuring it, if you have a WIFI Network at your home.
