> I'm not top posting. Given is a MusicXML file with 2 voices on one staff. Voice one contains a crescendo spanner.
musicxml2ly.py will create a ly file with faulty skips (hidden rests) or notes scrambled in chords. The reason is in musicxml.py line 1309 a direction wedge is added to any voice. This will lead to following voice elements: Voice1: 1. Note1 half at when=0 2. Note2 half at when=1/2 3. Direction wedge crescendo at when=1/2 Voice2: 1. Direction wedge crescendo at when=1/2 2. Note1 quarter at when=0 3. Note2 quarter at when=1/2 Subsequently in musicxml2ly line 2122 voice_bilder.jumpto (n.when) is called for any event in Voice1 which is ok and then in Voice2. 1. Direction wedge at when 1/2: will insert a skip 1/2 2. Note1 at when 0 will throw a warning about negative skip -1/2 3. Note2 at 1/2, ok Solution: I assume, direction wedges have to be coupled to specific voices?
