Other reviewer are right---the user interface is terrible
I bought Loopy HD after disregarding all the negative reviews about the user interface. I shouldnt have; it has a lot of potential, but the user interface is so cryptic that you wont figure it out even after watching instructional videos.
The other puzzling thing is that if you rotate the iPad to get your ports to suit your set-up, the interface is also rotated rather than remaining the same. I.e., the UI is sensitive to screen rotation, unlike most other apps. The net result is that that the control bar and buttons on it change position, depending on screen rotation, and this is very confusing.
There might be a setting to tweak that I have missed, but it is not for a lack of looking!
