hello all, i don't know if it is relevant, but my simple google search returned this software too:
http://loopauditioneer.sourceforge.net/ LoopAuditioneer is a software for evaluating, creating and manipulating loops and cues existing in wav file metadata. It's envisionaged to be useful for sample production for virtual pipe organs, like for instance GrandOrgue <http://sourceforge.net/projects/ourorgan/> software. SOURCE CODE: ------------ Is available on http://sourceforge.net/projects/loopauditioneer/ by SVN.
