changeset 39:796b3e3e053f
Changed MidiPlayer.java to allow the use of external sequencer programs (e.g. Garageband).
Changed Experiment.java to allow user to specify in commandline whether to use default MidiDevice (true), specified MidiDevice (0<variable<MidiDevs.length), or list the available devices on start up.
Changed ExperimentGui.java and SubjectDataPanel.java to add familiarity question if familiarity question isn't included at the presentation of each stimuli.
