While this process in traditional vinyl format was un-connectable from the speed at which a track played, some DJ softwares use their audio engine to allow DJs to incrementally adjust the key without altering the tempo.īecause tempo-locked pitch shifting works in the same way that keylock does (resampling the audio), you can’t get away with altering it too dramatically from the original key value – but it’s generally reasonable to move up or down a key, giving you a number of new options to use while mixing in key. Pitch-shifting isn’t just for rappers and Skrillex vocals, it’s actually a useful tool that allows DJs to alter the key of a song. Sounds like those garbled old pirated tracks from Napster that were horribly resampled, right?īut in this article, we’re going to talk about the other thing that many audio engines are capable of, keylocking’s often-ignored cousin: A QUICK INTRODUCTION TO PITCH SHIFTING Try it now – throw on a track with a solid melody, make sure keylocking is engaged, and listen to what it sounds like at +/-50%. The issue becomes that at more drastic adjustments in tempo, the keylocking algorithm is really put to the test, and the track begins to degrade in playback quality. Keylocking works by resampling the playing track at a different speed and readjusting the pitch to an equivalent offset to bring it back to “normal”. This makes more drastic beatmatching possible between songs that aren’t close in tempo, without turning your track into a slowed-down monster or high-speed chipmunk track. Keylocking in modern DJ software ( and on some turntables, like the Stanton STR8.150 at right) allows DJs to alter the tempo of a song without effecting the pitch – preventing tracks from becoming higher or lower pitched just because you want to mix them with another record.
But did you know that you’re able to manually adjust the key of a track in some DJ software to match it to the playing track? Read on to learn when this is possible and how to make it work with key detected tracks. Mixing in key is one of the best ways to create a smooth mix that resonates from track to track, increasing or decreasing energy in a way that makes sense to the ears of your audience.
