The UI does not show up completely on my IPad. I managed to navigate by memorizing the controls shown in demo videos but they do not show up either in standalone nor when used as an AU. I also attempted to navigate to a folder on my IPad where I have a lot of MIDI files stored but Files integration does not appear to be supported. Update: The developer was very responsive. He immediately responded to the reported problems and submitted an update to correct the problems! I have updated my rating and will support this developer. This app. is now one of my Go- to apps:)
