We have a "Specifications: Read First" list on each product page. Make sure to check that list before your purchase. Some of our templates using 3rd party plugins and/or Ableton packs are fully equipped with additional "Simpler" channels containing recorded versions of external tools inside of a Simpler device. Those Simpler devices can be found right below the channels with external content and only need to be activated (they are "off" by default). After that, you'll still get a "file missing" message, but you'll be able to play everything thats part of the template / track.
