Last year, Jason, aka DJ Puzzle, was at NAMM posting to our live blogs, this year he has a booth to showcase his long established Sountrackloops.com sample and loops libraries.
Soundtrackloops.com are amongst the first to make their libraries available in NI stems format - where you can mix between four separate stereo mixes. He showed us some Cuban examples. But Soundtrackloops cover a huge breadth of styles including many subgenres of current electronic music.
