I am looking for a MIDI interface for my 2010 macbook pro. I currently have a MAudio midisport 4x4 which has always served me well but it is USB powered and it seems that the macbook pro does not put out enough electricity over USB to power it. The USB light does not even turn on. I also only really need 1 in and 1 out so it is a little over kill. Almost all of the other MIDI interfaces I have seen are also USB powered so I am worried I will run into the same problem. Any suggestions?
