Could be promising, but can’t play midi file

I bought this to play MIDI files. First of all, I can’t get it to even find the file unless it is in my Applications directory or some subfolder because it starts there and the only other non-subdirectory you can get to is the root (/), to which it can’t go because it doesn’t have permission (and then you will be stuck). Even if I put the MIDI file there, find it and load it, I can’t get it to play. In fact, the Play MIDI button seems to be gone after successfully loading the file. Frustrating! I’d love to give this one a better review, but I’d also like to get my money back at this point.
