Dan, do you mean a simple soundfile that has loop markers embedded? I have tons of them.
Do you need .wav or .aiff or both? Mine are usually .wav but I can convert it to .aiff as well. I'll have to check on my old computer first to make sure whether the files header contain the loops.

I started with demo soundfile meta data reading/writing but now I need some sample files to work with. I saved a couple via Logic Pro X but the region info is saved as simple markers, not using instrument or sampler chunks.

I can reed the loop points externally with no problem. My problem is to set the loop points automatically from within Pd.

It's envisionaged to be useful for sample production for virtual pipe organs, like for instance <http://sourceforge.net/projects/ourorgan/> GrandOrgue software.
