User who asked the question (over email) also answered it. Thank you!
I have some good news for you ...
I found an iPhone layout, here, near the bottom of this thread and I downloaded it, emailed it and then opened the email on my iPhone and held down on the attachment to get the "open with" dialog and selected midi designer pro.
So far, so good. It loads and looks good.
I'm about to give it a try on my AT200.
