I'm using the Audio File Services API to get information like loop markers and so out of some AIFF files .
For marker informations one can use kAudioFilePropertyMarkerList.
But how can I get the root key ( the midi key that correspond to the original pitch of the AIFF file like e.g the EXS24 uses it )?
It looks like there is no chunk for that.
If you use AudioFileCountUserData / AudioFileGetUserDataSize / AudioFileGetUserData to walk through the chunks, do you encounter the InstrumentChunk? (see the ancient AIFF.h)
