// WHAT IT DOES
Stem DJing separates a track into 4 elements live: vocals, drums, bass, melody/other.
Each stem has its own volume knob. You can drop one element while keeping the others.
Available on rekordbox 6.6+, Stems-enabled CDJ-3000 firmware, and Serato Stems.

▸ HOW IT WORKS
▸ Signal flow — watch the dot
▸ SIGNAL FLOW
Glowing dot = your signal travelling through Live.
▸ LISTEN FOR
- • Backing vocal bleed when 'vocal off'
- • Drum stem bass bleed
- • CPU strain causing audio glitches
▸ WALKTHROUGH (5 steps)
- 1. DO: Enable Stems on Deck 1, play a vocal house track.▸ LISTEN: 4 stem knobs appear on the deck/app.
- 2. DO: Kill the vocal stem.▸ LISTEN: Track plays as instrumental only.
- 3. DO: Bring in Deck 2 (different track with vocals).▸ LISTEN: Two vocals avoided — only Deck 2 vocal heard.
- 4. DO: Try stem swap: kill Deck A bass stem, raise Deck B normally.▸ LISTEN: Bass swap without EQ touch.
- 5. DO: Watch CPU meter — disable stems on idle decks to save load.▸ LISTEN: Performance protection.
▸ COMMON MISTAKES
- ✗ Assuming clean stem separation — quality varies.
- ✗ Leaving stems on all decks — CPU overload.
- ✗ Treating stems as a gimmick — they're a transition tool.
