Key Areas

Decks — Each deck has a vinyl platter, waveform display, and performance pads. Deck A is on the left (cyan), Deck B on the right (purple).
Mixer — The center section has EQ knobs, channel faders, and the crossfader. Swipe to access more controls on iPhone.
Library — Browse your music collection at the bottom. Drag tracks onto decks to load them.

3 Loading Tracks

There are several ways to load music onto a deck:

Drag & Drop — Drag a track from the library onto either deck.
Double-Tap — Double-tap a track to load it to the next available deck.
Music Button — Tap the music note icon on a deck's transport bar to open the library filtered for that deck.
Files App — Import audio files from the Files app, iCloud, or external storage.

Once loaded, Tremor automatically analyzes the track for BPM and key. You'll see the waveform build and the BPM appear in the deck header.

💡

Pro Tip

Sort your library by Key to find harmonically compatible tracks. Mixing within the same key or adjacent keys always sounds good.

4 Your First Mix

Let's mix two tracks together. Follow these steps:

▶

Play Deck A

Load a track to Deck A and press PLAY. The waveform scrolls and the vinyl spins. This is your outgoing track.

♪

Cue Deck B

Load a second track to Deck B. Use CUE to preview in your headphones. Find the first beat.

↻

Match the BPM

Press SYNC on Deck B to match its tempo to Deck A. Or use the pitch fader to adjust manually.

✦

Drop & Blend

Press PLAY on Deck B at the right moment. Move the crossfader from A to B. Swap the bass EQ for a clean transition.

The EQ Swap Technique

For smooth transitions, don't just crossfade. Instead:

Keep the crossfader centered
Cut the LOW (bass) on Deck B
When ready to transition, swap the bass: bring B's LOW up while cutting A's LOW
This prevents bass frequencies from clashing
