While recently jamming on my Korg Volca Sample, I happened to discover a nice little trick which allows you to turn your Sample into a drone!
This trick can also be used for creating atmosphere, or endless oscillations

In basic terms, it can allow you to make a looped sample last forever, without using the sequencer and regardless of playback being on or off

Please check out a little tutorial I made of how to execute this in the link below -

Happy noise making!
