How it works

Three steps to a pro mix

No beatmatching practice. No music theory. No hours building a setlist.

1

Drop a folder

Point CortexDJ at your tracks. It analyzes every file — key, energy, BPM, intro/drop/outro — MIK-grade, and in seconds.

2

Pick the vibe & length

“One-hour warm-up set.” “Peak-time, 90 minutes.” The AI selects the right tracks, in the right harmonic order, on the right energy curve.

3

Mix, record, stream

Get a seamless, beatmatched mix with clean bass swaps and tasteful transitions. Export it, stream it to YouTube/Twitch, or perform it live on the decks.

Features

Everything a great mix needs — automatic

The analysis engine pros pay for, the mixing skill years take, built in.

🎯

MIK-grade analysis

Camelot key, 1–10 energy and exact BPM for every track — tuned to agree with Mixed In Key.

🎚️

Beatmatched transitions

Constant-tempo grids and phrase-aligned cues so the beats lock — no trainwrecks.

🎹

Harmonic mixing

Every blend follows the Camelot wheel, so keys never clash. Suggests your next track, too.

🔊

Clean bass swaps

One bassline at a time — a kick-synced low-end handover, never two basslines fighting.

📈

Energy-curve sets

Warm-up → peak → cool-down. Tell it the length and the vibe; it shapes the whole night.

📡

Record & live-stream

Bounce a master, capture HD video, or go live to YouTube, Facebook and Twitch.

🎛️

Full live decks

Prefer hands-on? A VirtualDJ-style console with EQ, FX, loops, hot-cues and pads.

🥁

Stem separation

AI splits bass, drums and vocals for cleaner swaps and vocal-clash avoidance.
