Key lock and changing key

Being in key isn’t just for musicians—it’s a powerful tool for DJs too. djay lets you control the key of any track, giving you more creative control over your mix. With Key Lock, you can change the tempo without changing the pitch. This means you can speed up or slow down tracks without making them sound unnatural.

You can also manually shift the key of a track up or down to match another song, create harmonic blends, or build entirely new moods. Whether you're beatmatching two club tracks, blending ambient layers, or performing a live remix, staying in key keeps your mix sounding smooth and musical.

These tools are great for beginners learning harmonic mixing, and essential for more advanced DJs looking to create next-level transitions and mashups.
