Find and read changes in key signature
Hi! I'm not sure how a plugin could identify a change in key signature within a score. I can find the key signature of a score (curScore.keysig) and process the value. But what about key changes in a piece? Thanx!

Upon a key change you would find a segment with the segmentType of KeySig

Thanks! After checking the sources again I also found cursor.keySignature, very helpful.

Yes, but how can one obtain the value of the key signature from a KeySig Element?

Thanks, but it doesn't seem to be working in a plugin.
The lines
if (el.type == Element.KEYSIG)
console.log('>>> KeySig key = ' + el.key());
return the response

Yes, you can access it from cursor as was mentioned above already.
You used to be able to read it from the element as well, but apparently that seems to be no longer working..

Yes, thank you.
Figured this one out by looking at the C++ code.

how can this work when I loop over segments (looping over cursor only goes over ChordRests) and want to know the keySignature at segments tick when Element.KeySig is encountered?
