I was wondering if there's a tutorial on how to create them... My google skill showed just a page of someone attempting and failing after 2 years due to the lack of informations about the process.
Is there a reference document accessible to most people or the best thing would be to "pair with someone that already knows how to do it"

I have a few ideas in mind and i wouldn't mind to make the audio selection/looping work in case.
In short any suggestin/direction is welcome!
