Here you can find the fingerings for all Orchidea multiphonics: https://berkeley.box.com/s/hih111gf1c29prypkdga88l8481g5kvl

They are not organised well and there is a Lisp script meant to be used to retrieve the specific image under a query that it’s not finished.

However, a way to retrieve the fingering is as follows: 

1. open the lisp script with a text editor 

2. search for the number of the multiphonics (eg. MulFl-mulvofl-N-N-fl_mph1302 -> 1302) 

3. this will go to a line where, at the end, there is the name of the picture containing the fingering 

4. check that the comment field is correct (eg. C flute Hummel) and you are not referring to Basson or so.
