Tremor

Real-time stem separation that starts in a second. Kill vocals, isolate drums, remix live — plus karaoke-synced lyrics and our biggest performance update yet.

Tremor — Professional DJ Mixer

Mix, scratch, and perform with a real DJ engine — not a wrapper around a phone music player. Tremor is built on a custom audio core, hand-tuned neural models running on-device, and a hardware-verified controller path that lets you take an iPhone or iPad seriously, all the way to a real gig.

WHY TREMOR • A custom low-latency audio engine designed for DJ work — not adapted from a music player • On-device AI — stem separation, beat detection, key detection, and song structure all run locally. Your music and listening data never leave your device • Hardware-verified controller support — what we list, we test • Multi-channel audio routing usually reserved for desktop DJ software

2-DECK & 4-DECK MIXING 2-deck and 4-deck modes with independent 3-band EQ, filters, and effects. Smooth crossfading with multiple curve types, including an orbital fader for 4-deck blending.

AI-POWERED AUDIO INTELLIGENCE • Real-time stem separation — isolate vocals, drums, bass, and other instruments on the fly • Neural beat detection with automatic BPM and downbeat tracking • Musical key detection for harmonic mixing • Mood, energy, and genre classification • Song structure analysis — intro, verse, chorus, drop, outro

VINYL SCRATCHING Touch the turntable to scratch with realistic platter physics. Adjustable motor speed, platter feel, smooth inertia, and authentic pause/resume behavior.

BEAT SYNC One-tap beat sync locks tempo and phase between decks. Automatic BPM matching powered by neural beat detection.

DJ CONTROLLER SUPPORT Hardware-verified support for Pioneer DDJ-FLX2, DDJ-FLX4, and DDJ-FLX10. Customize the mapping of any control through the built-in MIDI Settings.

MULTI-ROUTE AUDIO Send master audio and headphone cue to separate channels on a 4-channel USB audio interface, so you can pre-listen with full PFL while your master output plays to speakers.

PERFORMANCE FEATURES • 16 hot cue pads per deck • Beat-synced loops and loop rolls • Beat jump • Color FX and Sound FX • Sampler with 16 slots per deck • Video on vinyl — play music videos on the turntable platter

STREAMING & SOURCES • Tidal, Apple Music, SoundCloud, and local library • Shazam song identification and lyrics display • AirPlay video streaming • RTMP live streaming to YouTube, Twitch, and Facebook • CarPlay support for in-vehicle playback

DESIGNED FOR • DJs learning beat-matching at home • DJs practicing for their next set • DJs playing real gigs — alone, on a controller, or paired with a club system • Live streamers broadcasting to YouTube, Twitch, and Facebook
