Tremor - Professional DJ Mixer Mix, scratch, and perform with a real DJ engine - not a wrapper around a phone music player. Tremor runs on a custom audio core, hand-tuned neural models on-device, and a hardware-verified controller path - now native on Mac, iPhone, and iPad. WHY TREMOR . A custom low-latency audio engine built for DJ work - not adapted from a music player . On-device AI - stem separation, beat, key, and song-structure detection run locally. Your music and listening data never leave your device . Hardware-verified controller support - what we list, we test . Pro-grade routing and effects usually reserved for desktop software, now on all your devices 2-DECK & 4-DECK MIXING 2- and 4-deck modes with independent 3-band EQ, filters, trim, and effects. Smooth crossfading with multiple curve types, plus an orbital fader for 4-deck blending. AI AUDIO INTELLIGENCE . Real-time stem separation - isolate vocals, drums, bass, and other instruments live . Neural beat detection with automatic BPM and downbeat tracking . Musical key detection + Camelot for harmonic mixing . Mood, energy, and genre classification . Song-structure analysis - intro, verse, chorus, drop, outro YOUR AI CAN DJ (MAC) Turn on AI Agent Access and AI assistants on your Mac - Claude Code, Claude Desktop, Copilot, Codex, Antigravity, VS Code, or Cursor - take the decks: plan a set with a quick interview, dig your library or SoundCloud, mix with beat-locked transitions, scratch with real fader choreography, and drum live on a built-in instrument kit. All local - loopback-only, off by default, one toggle to revoke. VINYL FEEL & SCRATCHING Touch the platter to scratch with realistic physics - adjustable motor speed, platter feel, smooth inertia, vinyl character (wow & flutter, needle click), and authentic pause/resume. PERFORM . 16 hot-cue pads per deck . Beat loops, manual loops, and rekordbox-style loop resize . Beat jump, key shift, keyboard mode . 16-slot sampler with custom samples, per-pad gain, and per-pad sequencing - loop or one-shot, beat-quantized launches, latched rolls . Three built-in DJ drops - including one voiced by Tremor's own AI . Beat FX and Sound Color FX . Host third-party Audio Unit (AU) effects - bring your favorite plug-ins to the decks BEAT SYNC & HARMONIC MIXING One tap locks tempo and phase between decks. Find Compatible Tracks surfaces songs in key and tempo so every transition lands. LOUDNESS DONE RIGHT Per-track LUFS normalization (EBU R128) levels every track automatically - no more riding the trim between songs. DJ CONTROLLER SUPPORT Hardware-verified support for Pioneer DDJ-FLX2, FLX4, and FLX10, plus Numark Mixtrack Platinum FX and DJ2GO2. Remap any control in the built-in MIDI settings.

Previous Versions
Here you can find the changelog of Tremor: AI DJ Mixer & Stems since it was posted on our website on 2016-09-30 17:06:23.
The latest version is 3.3.1 and it was updated on 2026-10-07 08:38:46. See below the changes in each version.
Tremor: AI DJ Mixer & Stems version 3.3.1
Updated At: 2026-10-06
Changes: Version History FIXES
• The video mix preview shows right away instead of staying black until the crossfader moves
• Untagged files get a clean title and artist instead of a raw filename, and identified names and cover art stick without re-probing
• Rate Tremor from Settings 3.3.1 Sep 23 The sampler grew up. Every pad now has its own behavior: loop or one-shot per pad, launches quantized to the beat grid, and latched repeat rolls — set them in the new pad editor (edit mode → tap any pad), where custom samples also get their own gain control. A third built-in DJ drop joins pads 1–2 — synthesized, stutter-cut, and mixed in-house. Plus: cleaner waveforms on high-energy tracks, a fixed low band in beat-grid views, better 4-deck layouts on iPhone and iPad, per-stem reverse rolls, and a stack of fixes from live set testing. 3.3 Aug 31 STEMS, EVERYWHERE YOU MIX
This update makes real-time stem separation dramatically faster, smarter, and rock-solid — even on older iPhones and long DJ edits:
• Stems now prepare fairly across all decks and follow your playhead, so the part you're about to play is always ready first
• Instant reloads — waveforms and stems for tracks you've played before appear in a fraction of a second
• Major stability work for 4-deck sessions and low-memory devices
4-DECK VIDEO MIXING
Full-screen video mix on iPhone, per-deck visualizer planes for audio-only tracks, album-art rotation, and recording that follows your deck view — with perfectly synced audio.
SAMPLER ONE-SHOTS
Pads now fire one-shot by default (hold-to-loop available in Settings).
SMARTER TRACK IDENTIFICATION
Tremor now fuses what your files say with what the audio says — fixing mislabeled downloads without ever overwriting a correct name, and pulling in verified artwork.
Plus: the track-load audio glitch on AirPlay is gone, track repeat is now gapless, and dozens of performance and stability improvements throughout. 3.2 Aug 18 Realtime Stems, supercharged
• Stem separation starts in about a second — and vocal removal sounds dramatically better from the very first moments, sharpening further as the track plays
• Previously separated tracks load their stems almost instantly
• Your stem selections now carry over when you load a new track
Karaoke-ready lyrics
• Synced lyrics with karaoke-accurate word highlighting
More for your setup
• Microphone talkover with automatic music ducking
• 4-channel USB headphone cueing on supported controllers
• Improved DJ controller support and LED feedback
Fixes
• Fixed an audio glitch when loading a new track with stems active
• Fixed a rare playback stall after pausing
• Many stability improvements under the hood 3.1 Jul 24 Version 3.0 — rebuilt from the ground up.

Tremor: AI DJ Mixer & Stems version 3.2
Updated At: 2026-08-27
Changes: Version History STEMS, EVERYWHERE YOU MIX
This update makes real-time stem separation dramatically faster, smarter, and rock-solid — even on older iPhones and long DJ edits:
• Stems now prepare fairly across all decks and follow your playhead, so the part you're about to play is always ready first
• Instant reloads — waveforms and stems for tracks you've played before appear in a fraction of a second
• Major stability work for 4-deck sessions and low-memory devices
4-DECK VIDEO MIXING
Full-screen video mix on iPhone, per-deck visualizer planes for audio-only tracks, album-art rotation, and recording that follows your deck view — with perfectly synced audio.
SAMPLER ONE-SHOTS
Pads now fire one-shot by default (hold-to-loop available in Settings).
SMARTER TRACK IDENTIFICATION
Tremor now fuses what your files say with what the audio says — fixing mislabeled downloads without ever overwriting a correct name, and pulling in verified artwork.
Plus: the track-load audio glitch on AirPlay is gone, track repeat is now gapless, and dozens of performance and stability improvements throughout. 3.2 Aug 18 Realtime Stems, supercharged
• Stem separation starts in about a second — and vocal removal sounds dramatically better from the very first moments, sharpening further as the track plays
• Previously separated tracks load their stems almost instantly
• Your stem selections now carry over when you load a new track
Karaoke-ready lyrics
• Synced lyrics with karaoke-accurate word highlighting
More for your setup
• Microphone talkover with automatic music ducking
• 4-channel USB headphone cueing on supported controllers
• Improved DJ controller support and LED feedback
Fixes
• Fixed an audio glitch when loading a new track with stems active
• Fixed a rare playback stall after pausing
• Many stability improvements under the hood 3.1 Jul 24 Version 3.0 — rebuilt from the ground up.
