This section groups techniques that were developed using older versions of Beat Link Trigger, before many important discoveries and advances were made. They still work, but are usually not necessary; there are easier ways of doing things today.
For example, because Crate Digger now makes it possible to get track metadata even when there are four CDJs in use, there is not any reason to go to the trouble of working with a DJ to set up a metadata cache before a show.
The fact that we now can rely on metadata like this made it worth building the Show interface to do the work of matching tracks and arranging cues on them, which eliminates the need for the kinds of clever tricks we previously used to try to manually recognize them. And there’s now a built-in playlist writer that does a more thorough job than the sample code shown at the end of the Matching Tracks section.
