Track Info Bar Anatomy
Each deck has a Track Info Bar that displays track metadata, a waveform visualization, and quick-access buttons. Here's what each element does:
Component Details
| Element | Function | Interaction |
|---|---|---|
| Album Artwork | Shows album art or a generic vinyl image if unavailable | Tap to expand artwork view |
| Track Title | Displays song name and artist | Shows source badge (Apple Music, SoundCloud, Files) |
| Waveform | Visual representation of the audio with playhead position | Tap to cycle display modes, drag to scrub |
| Shazam Button | Identifies the currently playing track using the microphone | Tap to start listening, results appear in a sheet |
| Music Info | Shows AI-detected genre, energy, danceability, and mood | Tap to open popover with full classification details |
| Lyrics Button | Displays synced lyrics for the track | Tap to open lyrics sheet with karaoke-style highlighting |
Compact Mode
On smaller screens or in 4-deck mode, the Track Info Bar collapses to a compact drawer. Tap the expansion handle to reveal the full controls.
Waveform Display Modes
The waveform visualization can be switched between 6 different display modes. Tap the waveform to cycle through modes, or use a DJ controller's waveform mode button.
〰️ Envelope
Classic min/max envelope style showing the audio amplitude as a filled shape. Similar to what you see in audio editing software. Shows the full track overview with frequency-based coloring.
📊 Bars
Vertical bar visualization with each bar representing a segment of audio. Bars are colored by frequency content: blue for bass, green for mids, magenta for highs.
📈 Scrolling
A moving waveform that scrolls as the track plays. The playhead stays centered while the waveform moves underneath. Good for following the current position in real-time.
🎵 Beats (Zoomed)
Zoomed scrolling view with beat grid overlay. Shows approximately 4-8 beats around the current position. Beat markers appear as vertical lines, with beat 1 (downbeat) shown thicker. Essential for beatmatching.
🔊 Oscilloscope
Real-time oscilloscope visualization showing the actual audio waveform as it plays. Features subtle smoke/glow effects. Great for visual feedback during scratching and drops.
⬛ Dual Deck
Split view showing both Deck A and Deck B waveforms simultaneously. Useful for visual beatmatching and comparing track structures between decks.
Waveform Colors
Waveforms are colored based on frequency content to help you identify different parts of the track at a glance:
- Blue/Cyan — Low frequencies (kick drums, bass)
- Green — Mid frequencies (vocals, snares, guitars)
- Magenta/Pink — High frequencies (hi-hats, cymbals, synth highs)
This coloring lets you visually identify drops (lots of bass = blue), breakdowns (vocals = green), and build-ups (rising highs = pink).
Waveform Scrubbing
The waveform isn't just for display — it's an interactive control for navigating through your track.
Scrubbing Gestures
| Gesture | Action |
|---|---|
| Tap anywhere | Jump to that position in the track |
| Drag horizontally | Scrub through the track (playhead follows finger) |
| Pinch (in Beats mode) | Zoom in/out to see more or fewer beats |
Audio While Seeking
Enable Audio While Seeking in Settings to hear the audio as you scrub through the waveform, CDJ-style. When disabled, you only hear audio during normal playback.
Beat Grid & Markers
In Beats (Zoomed) mode, the waveform shows the detected beat grid overlaid on the audio.
Understanding Beat Markers
- Thin vertical lines — Individual beat positions (beats 2, 3, 4)
- Thick vertical line — Beat 1 (downbeat) of each bar
- Center playhead — Current playback position
- Hot cue markers — Colored triangles at saved cue positions
- Loop region — Highlighted area when a loop is active
Correcting the Downbeat
If the automatic beat detection placed beat 1 in the wrong position, go to the SYNC page and tap the TAP button exactly on the first beat of a musical bar. This shifts the beat grid so that position becomes beat 1.
Music Info Popover
Tap the chart icon (📊) on any deck to see AI-detected music classification for the loaded track.
