>On A DJ Tip
While we’re talking mixing, there’s also that other type of mixing, as employed by DJs and live performers. Mixing in that context is largely built on the literal mixing and matching of distinct tracks, and – as with all areas of music making – freeware abounds. Mixxx.org is a communitydriven open source piece of freeware that provides an allin-one hub for BPM and key detection as well as effectchaining and DJ controller support. There’s also Cross DJ that offers a simple way to meld tracks, though it’s likely you’ll hunger for the more advanced features that come in the paid version.
