import pdf

I've been running an experiment with import pdf and come to the conclusions

The function is a little more accurate if you present it with the voice part alone than if you present it with voice plus piano
The function occasionally inserts a note way below the stave two octaves below the previous note
It regularly inserts an 1/8 note rest instead of continuing the previous very short note

The files here are
voice only - the voice part I get what I get when importing a voice only score
all parts - the voice part I get what I get when importing an all parts core

I hope this helps
