Yamaha: Set List Organizer (iPad)

[iPlogger]

Does anyone have experience using the Yamaha Set List Organzier for the iPad? I am very interested in it but want to know if it's as good as it seems.

Among other things, I use a Yamaha S90XS and I'm constantly hopping around selecting patches. And the levels across the sounds are all over the place. I'm looking for a patch change app I can click and immediately switch patches and have the volume match the rest of the sounds. It looks like I can do that with this.

A new twist happened last night, too. It was fairly dark and I could not see the layout panel to switch my sound. Having this app will help me out with any low light situations, too.

Thanks for any advice/help.
