mplay doesn't work once it has been closed

MWE

julia> using MIDI, Mplay

julia> mplay(testmidi())
Note retriggered
Note retriggered

julia> mplay(testmidi())
midi: cannot open MIDI output

Julia has exited. Press Enter to start a new session.

So, open the GUI through mplay, and then close it (normally close the window, press the X button at top right). If you try to open mplay again, it doesn't work.

@jheinen any idea how can this be solved / if this can be solved? (related with #5 ).

I am guessing that it comes from global player , but I am not sure....

Is there a reason for it to be global? Can't it be passed as a first argument to all functions in the module?
