Does not work with iConnectivity 2 and iPhone 6S

Let me start by saying the sample sounds are wonderful. I purchased this app because it says right there in the info works with iOS 3.1 and higher does not say except iPhone 6S so I would assume it should work. It also says it works with iConnectivity 2 dock it does not. Ok to be fair I do not know which is at fault but I do know there is no configuration menu or a way to enable or any mention of midi in the set menu or the manual. I am therefore of the opinion that I got ripped off and that the manufacturer is listing this app under false pretense.
Beware if you intend to use an external controller.
