cout << "Altering notes\n";
DOMNodeList *notes = measure->getElementsByTagName(XS("note"));
for( int i=0; i<notes->getLength(); i++ ){
DOMElement *note = (DOMElement*)notes->item(i);
//cout << "note " << i << endl;
DOMElement *durEl = getSingleElement(note,"duration");
if( durEl != NULL ){ // grace notes have no duration
