Implemented instruments (High, Mid, Low, Sub) by simply transposing pitch by octaves (+1, 0, -1, -2). Cleaned up MInC_Sequencer class member variables/properties. Set default volume of pulse sequencer to 0.5 * 0.5 amplitude. Fixed broken connection between volume slider and pulse sequencer. Changed response to Next button from touch up to touch down. Removed Traffic and Piano Phase images and .xml files from project.
