Understand what you hear
Tap along with the beat, at least 4 times.
What is BPM?
Beats per minute. Chill songs sit around 70–95 BPM, pop and funk 100–125, house 120–128, drum & bass around 170.
Major vs minor
The key is a song's home. Major sounds bright, minor sounds moodier. Every major key has a relative minor that uses exactly the same notes, like C major and A minor.
What do I–V–vi–IV mean?
Roman numerals show where a chord sits in the scale. Uppercase is major, lowercase is minor. I–V–vi–IV powers thousands of pop songs.
The Camelot wheel for DJs
Camelot gives each key a code like 8A or 10B. Tracks with the same number, or one number apart with the same letter, blend without clashing.
How to make a smooth transition
Hit SYNC to match tempo, start the next track at the top of a phrase (every 8 or 16 beats), cut the bass of the outgoing track with the EQ, then slide the crossfader slowly.
DJ
Two decks, one groove
SYNC matches tempo and beat to the other deck. AUTO keeps the set going with the best next track.

froppy 2.0 · L6 EQ Frog. BPM and key detection for your own files runs on your device; nothing is uploaded. Spotify and Apple Music keep their audio protected, so their songs drive the visuals by tempo rather than by sound, and can't be loaded into the DJ decks.
