Consult the code to see how it works. To use, call `converter.registerSubConverter(converter.qmConverter.QMConverter)` then `myStream = converter.parse('quarterMusic: C E G D F')` ) annotations) converter) environment)meter)note)streamzconverter.qmConverterc0eZdZdZdZdZddZddZddZy) QMConverter)qm quarterMusic)r Nc@|j}tj}tjd}|j d||D]9}t j|}d|j_ |j|;|j|_y)a Parse the data.
