Tremor: AI DJ Mixer & Stems

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 — native on Mac, iPhone, iPad, and ready for iPhone Duo. 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 • Pro-grade routing and effects on every device 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 — motor speed, platter feel, inertia, vinyl character (wow & flutter, needle click), and authentic pause/resume. REAL TURNTABLES (CONTROL VINYL) Serato, VirtualDJ, or rekordbox control vinyl drives the decks through a USB audio interface; a regular record plays straight through with live waveforms, and Tremor identifies it. Auto mode tells them apart. 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 • Beat FX and Sound Color FX • Host third-party Audio Unit (AU) effects on 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.
