Hallo

I've tried to change the key names.
(see attachments)

I've also made other changes. This is not the best, but a little optimised
... (d -> low-d
ees -> e [both side]
e -> m-e [left-hand middle-e]
e -> gis,
f -> low-es,
gis -> f)

I've not tested the (text? . ("F" . 0)) construct.

I'm not trying to create a convert-ly.

Thanks for the other answers.

Markus

It looked like Marcus supplied some updated code for the woodwind diagrams. Has this been picked up?
