I found several posts on the TalkBass.com forum about them having problems with IOS 8.x and newer with the 12-Step. I have 8.3 on all my devices. Have these issues been sorted out? I just ordered a 12-Step and really need it to work with IOS8.
PS... Here is the text of that post:OK, I updated my iPhone 5 to 8.02 and Animoog to 1.1.5 and the 12-step still isn't recognized! Bummer. CoreMIDI was upgraded in iOS 8 so I'm guessing that has something to do with it. My Korg nanoKey still works like a charm. Garageband also works fine with the nanoKey but not the KMI 12-step. If this doesnt get resolved there is no reason for me to own the 12-step
Later post to my question "Is it fixed?"not to my knowledge. i sold my 12-step. good luck.
