TUTORIAL

Your First Mix

Learn the basics of mixing in Kuartz with this step-by-step guide. In just a few minutes, you'll create your first seamless transition.

Kuartz main interface overview
1

Load Your First Tracks

Start by adding two tracks to your timeline. This is where Kuartz differs from traditional DJ software - you'll arrange your tracks visually on a timeline, similar to a DAW.

From the Browser

  1. 1. Navigate to your music folder in the browser panel
  2. 2. Click on a track to select it
  3. 3. Drag the track onto Deck 1 in the timeline
  4. 4. Repeat for your second track on Deck 2

Pro Tip

Wait for the analysis to complete (check the Status column) before adding tracks. This ensures BPM and key information is available for sync and harmonic mixing.

2

Match the Tempo

Unlike traditional DJ software where each deck has its own tempo, Kuartz uses a global BPM. All tracks are time-stretched to match this master tempo, keeping everything perfectly in sync.

Setting Global BPM

  • • Look at the BPM display in the top bar
  • • Click the value to type a specific BPM
  • • Or drag up/down for fine adjustment
  • • Use +/- buttons for 0.1 BPM changes

Choosing the Right BPM

Set the global BPM close to your tracks' original tempo. Large tempo changes (more than 8%) may affect audio quality. For best results, choose tracks with similar BPMs.

3

Position Your Transition

The magic of timeline mixing is seeing exactly where your tracks overlap. Position the second track so it starts playing before the first track ends - this overlap is your transition zone.

Moving Clips

  • • Click and drag the center of a clip
  • • The clip snaps to the beat grid
  • • Release to place the clip

Trimming Clips

  • • Drag the left edge to set start point
  • • Drag the right edge to set end point
  • • Perfect for cutting intros/outros

Overlap Length

A typical transition is 16-32 beats (4-8 bars). Start with longer overlaps while learning - they're more forgiving.

4

Blend with EQ

The EQ is your main tool for smooth transitions. The key is to avoid having two bass lines playing at full volume simultaneously - they'll clash and sound muddy.

Basic EQ Transition

  1. 1. Start with Track 2's LOW EQ at minimum (cut)
  2. 2. As you approach the transition point, gradually bring Track 2's LOW up
  3. 3. Simultaneously cut Track 1's LOW
  4. 4. The "bass swap" is when you exchange the lows

The Filter Alternative

Instead of EQ swaps, try the Xone-style filter. Sweep it from center toward highpass on Track 1 while sweeping Track 2 from lowpass toward center. This creates a smooth, sweeping transition effect.

5

Control the Energy

Use the volume faders to control the relative levels of each track during the transition. This helps maintain consistent energy and prevents your mix from getting too loud in the overlap.

Volume Faders

  • • Drag the triangle markers on the VU meter
  • • Watch the meters - avoid red (clipping)
  • • Double-click to reset to 0dB
  • • Use headroom setting if needed

Preview in Headphones

Click the headphone button on a track to preview it in your headphones without affecting the main output. This lets you cue up the next track and check your mix before it goes live.

6

Play and Refine

Now it's time to hear your mix! Press Space (or click Play) to start playback. Listen to the transition and make adjustments as needed.

What to Listen For

  • • Beats should stay aligned
  • • No bass clashing
  • • Smooth energy flow
  • • No sudden volume jumps

Make Adjustments

  • • Pause and reposition clips
  • • Adjust EQ settings
  • • Try different overlap lengths
  • • Experiment with the filter

Save Your Work

Use File → Save Project to save your timeline. You can come back later to continue refining or add more tracks to build a full set.

TIMELINE

Timeline-Based Mixing

The timeline is the heart of Kuartz. Unlike traditional DJ software with two decks, you work on a visual timeline where you can see your entire set, plan transitions in advance, and make adjustments on the fly. Think of it like a DAW for DJing.

Kuartz timeline with multiple clips and transition overlap

Understanding the Timeline

The timeline displays 4 horizontal tracks (decks), each capable of holding audio clips. Time flows from left to right, and the vertical playhead shows the current playback position. When two clips overlap horizontally, both play simultaneously - this is where your transitions happen.

Timeline Elements

  • Beat Grid - Vertical lines showing beats and bars for alignment
  • Playhead - The vertical line indicating current position
  • Clips - Audio regions showing waveforms
  • Track Controls - Mixer strip on the left of each track

Zoom Levels

The grid adapts to your zoom level:

  • • Zoomed in: See individual beats
  • • Medium zoom: See 4-8 beat groupings
  • • Zoomed out: See 16-128 beat sections

Use pinch gestures or scroll to zoom.

Navigation

Action Result
Scroll wheel (vertical) Navigate between tracks vertically
Scroll wheel (horizontal) Pan through the timeline
Pinch gesture (trackpad) Zoom in/out horizontally
Magnify gesture Zoom centered on cursor position
Click on empty area Move playhead to that position

Working with Clips

BPM & Key Controls

Clip BPM (20-300)

The detected BPM of the original track. You can manually adjust this if the detection was incorrect.

  • • Click value to type directly
  • • Drag vertically for continuous adjustment
  • • Use +/- buttons for fine control (auto-repeat when held)

Note: If the detected BPM is half or double the actual tempo, adjust it here. The track will then sync correctly with your global BPM.

Musical Key

The detected musical key of the track. Displayed in Camelot notation for easy harmonic mixing.

  • • Select from dropdown (12 keys available)
  • • Color-coded for Camelot wheel compatibility
  • • Used by AI recommendations for harmonic mixing

Gain & Analysis

Gain Knob

Adjust the clip's volume level. Use this to match loudness between tracks so transitions are smooth without sudden volume changes.

AUTO (Normalize)

Toggle automatic gain normalization. When enabled, Kuartz automatically adjusts the gain to match other tracks in your set.

Reanalyze

Re-run the analysis to detect BPM, key, and energy. Useful if you've modified the track or if initial detection was inaccurate.

Cue Points & Markers

Markers help you navigate within a track and identify important sections like drops, breakdowns, or vocal entries.

Marker Types

  • IN - Start point for the clip
  • OUT - End point for the clip
  • Normal - General cue points for navigation

Marker Actions

  • Click badge - Jump to marker position

MIXER

Track Controls

Each of the 4 decks has a full channel strip with professional mixing controls. The mixer is displayed vertically on the left side of each track in the timeline, giving you immediate access to EQ, filter, volume, and routing controls.

Kuartz Mixer channel strip showing EQ, filter, volume, and buttons

Channel Controls

Each channel has routing buttons that control where the audio goes. Click on a track's number to focus it (shown with blue border), which selects that deck for any focused operations.

M

Mute

Completely silences this track in the master output. The track keeps playing but you won't hear it.

S

Solo

Hear only this track - all other non-soloed tracks are muted. Multiple tracks can be soloed.

Preview (Cue)

Sends this track to the Preview output (headphones). Independent of Mute/Solo - you can preview a muted track!

A

Automation

Reserved for future automation features. Currently disabled.

Filter (Xone-Style)

The filter is modeled after the legendary Allen & Heath Xone:92 filter, known for its smooth, musical sweeps. It's a single knob that transitions between highpass and lowpass filtering with a bypass point in the center - perfect for building tension or creating dramatic sweeps during transitions.

Highpass (Left)

Removes bass and low-mids. Turn fully left for maximum HP effect (100%).

Center (Bypass)

No filtering applied. This is the default position for normal playback.

Lowpass (Right)

Removes highs and presence. Turn fully right for maximum LP effect (100%).

Transition Technique

For smooth transitions, try sweeping the outgoing track's filter toward highpass while sweeping the incoming track from lowpass toward center. This creates a natural crossover effect where frequencies "hand off" from one track to another.

3-Band EQ

A professional 3-band equalizer with isolator-style "kill" capability. Each band ranges from -50dB (complete cut) to +6dB boost. The curve uses logarithmic scaling for precise control in the cut range, and at the minimum position, the band is completely silenced (cut-to-infinity).

HIGH

Controls treble, cymbals, hi-hats, and vocal sibilance. Cut the highs during transitions to reduce harshness.

MID

Controls vocals, synths, and melodic content. Cutting mids can help two tracks blend without clashing melodies.

LOW

Controls kick drums and bass. Essential for the "bass swap" technique - never have two bass lines at full volume together!

Tip: Double-click any EQ knob to instantly reset to 0dB (unity).

Note: The knob arc starts from center (0dB), making it easy to see if you're boosting or cutting.

Volume & Sends

Volume Fader

  • Range: -50dB to 0dB with cut-to-infinity
  • Drag the triangle markers to adjust
  • Double-click to reset to 0dB
  • VU meter shows real-time L/R levels

  • SEND 2 - Route to FX bus 2 (0-100%)
EFFECTS

Effects & VST Plugins

Add depth and creativity to your mixes with built-in effects or your favorite VST/AU plugins. Effects can be applied to the master output, send buses, or external routing for maximum flexibility.

Kuartz Effects panel with rack selector and effect slots

Effect Racks

Effects are organized into racks. Each rack processes audio from a specific bus. Click on a rack selector button to switch between them - each button shows a real-time VU meter indicating the audio level on that bus.

MASTER

Effects applied to the final mix output. Use for mastering effects like limiters or subtle compression.

SEND 1

Shared effects bus. Use the SEND 1 knob on each channel to control how much signal goes here.

SEND 2

Second shared effects bus. Great for having reverb on SEND 1 and delay on SEND 2.

EXTERNAL

Effects for external routing mode. Processes audio going to separate physical outputs.

Send Effects vs Insert Effects

Send effects (SEND 1/2) are shared - multiple tracks can use the same reverb, saving CPU. Insert effects (MASTER) process the entire signal. For per-track effects, use the channel filter/EQ or add effects to the master with careful gain staging.

Built-in Effects

Kuartz includes essential DJ effects, optimized for low latency and high quality.

Reverb

Adds space and depth. Great for vocal atmospheres and transition effects.

Delay

Echo effect synced to BPM. Creates rhythmic patterns and builds tension.

LowPass

Cuts high frequencies. Useful for creating underwater or muffled effects.

HighPass

Cuts low frequencies. Creates thin, telephone-like sounds for buildups.

DropMaximizer

Loudness maximizer designed for drops. Adds punch and presence.

Effect Controls

Each effect slot displays its controls in a consistent layout. Effects can be chained (processed in order) and reordered by dragging.

Per Effect Slot

  • Bypass (●) - Green when active, toggles the effect. Use to A/B compare.
  • Effect Name - Shows which effect is loaded
  • Menu (⋮) - Remove effect from rack
  • Parameter Knobs - Adjust dry/wet, time, feedback, etc.

Rack Management

  • Drag effect slots - Reorder the processing chain
  • Click + button - Add new effect from menu
  • Up to 10 effects - Per rack maximum

VST & AU Plugin Support

Use your favorite studio plugins live in your DJ sets. Kuartz supports AU (macOS) and VST3 (64-bit) plugins, so any effect that works in your DAW will work here.

Supported Formats

  • • AU (Audio Unit) - macOS
  • • VST3 (64-bit) - macOS/Windows

Managing Plugins

Go to Settings → VST Plugins to scan for plugins and manage which ones are available in the effect menu.

Performance Note: VST plugins can be CPU-intensive. Monitor the CPU indicator in the top bar. If you experience audio dropouts, try reducing the number of active plugins or increasing buffer size.

App Store Version: If you downloaded Kuartz from the Mac App Store, some VST/AU plugins may not work due to macOS sandbox restrictions. Many plugins require system access that the sandbox blocks. For full plugin compatibility, download the direct version from our website.

AI CO-PILOT

Mix Recommendations

Stop scrolling through thousands of tracks. Kuartz AI analyzes BPM, key, energy, and musical characteristics to suggest tracks that will actually work next in your mix.

Kuartz mix recommendations panel with direction buttons and track suggestions

How It Works

The recommendation engine considers multiple factors to find tracks that will mix well together:

BPM Compatibility

Finds tracks within a mixable tempo range to avoid extreme time-stretching.

Harmonic Matching

Uses the Camelot wheel to find tracks in compatible musical keys.

Energy Level

Considers track intensity (0-100) to control your set's energy flow.

Smart Analysis

AI combines all factors to rank the best overall matches.

Mix Directions

Choose how you want to shape your set's energy. Each direction filters recommendations differently.

Energy Match

Keep the vibe steady. Finds tracks with similar energy to your current one.

Energy Boost

Build the energy up. Shows tracks with higher intensity for peak moments.

Energy Drop

Bring it down. Perfect for breaks, cooldowns, or transitioning to chill sections.

Harmonic Mix

Key-focused. Prioritizes Camelot wheel compatible keys for melodic blending.

Smart Mix

AI's best picks. Balances all factors for the most natural transitions.

Getting Recommendations

Step by Step

  1. 1. Right-click a track in the browser or timeline
  2. 2. Select "Mix Recommendations" or "Get Recommendations"
  3. 3. Choose your desired mix direction
  4. 4. Browse the recommended tracks with BPM, key, and energy info
  5. 5. Drag your chosen track directly to the timeline
