Personally, I think this is a pretty decent, well designed application; it not only allows the user to download and listen to midi files on their Apple Device, but also includes a number of powerful editing features that rival software programs written for desktop computers. One feature that could be added is the ability to transfer files directly in iTunes. An integrated browser would also facilitate the downloading of additional midi files from the Internet. The included WiFi interface works well, but permits the transfer of only one file at a time, making the task of moving files back and forth between App and PC/Mac a very laborious affair. This is the only reason why I rate this application 4 Star instead of 5.
