BeatMeister is a dual-deck DJ app designed for iPad, iPhone, and Apple Vision Pro. Load tracks from your music library onto two independent decks and start mixing with a full suite of tools built for live performance. AI Stem Separation Isolate vocals, drums, and melody using on-device AI. Mute the vocals for an instant instrumental, drop the drums for a breakdown, or boost the melody — all with independent per-stem volume knobs. No internet connection required. 16 Instant Effects Two banks of 8 press-and-hold effects with smooth intensity ramping. Spin throws, echo loops, granular freeze, flanger, wobble bass, bitcrusher, reverb wash, and more. Customize ramp-up and ramp-down times to match your style. 2D FX Pad Touch and drag across an X-Y pad to modulate effects in real time. Choose from 12 effect types including low-pass filter, high-pass filter, ring modulator, echo, glitch, distortion, and auto-pan. Use the lock option to keep the effect going after touch release. Scratch Wheel An 8-sector circular controller with frequency-based waveform visualization. Tap sectors to jump or slice while keeping the tempo. Swipe to scratch. See your track's bass, mids, and highs displayed as color-coded rings. Beat-Synced Everything Automatic BPM detection with tap tempo override. Quantized loops (1/4 to 32 beats), beat-synced seeking and jumping, and auto DJ transitions that crossfade perfectly on the beat. Full MIDI Controller Support Plug in your Pioneer DDJ-FLX4, DDJ-FLX2, or any MIDI controller. Map every fader, knob, button, and jog wheel with 14-bit precision. Save custom presets per device. Sample Pads 8 built-in drum and sound effect pads plus 8 customizable pads for your own samples. Load WAV, MP3, M4A, or AIFF files and trigger them live. 5-Band EQ & Mixer Shape your sound with low, mid, high, filter, and gain controls per deck. Monitor levels with real-time stereo power meters and blend decks with the crossfader. Mix Recording Record your entire set to high-quality M4A and save it to your music library. One-tap record with elapsed time display. Auto DJ Enable beat sync and auto fader for hands-free transitions. BeatMeister matches tempo between decks and smoothly crossfades over 32 beats. More Features • Pitch-preserving time stretch for speed changes • Real-time frequency waveform visualization • Track artwork as blurred deck backgrounds • Customizable FX button mapping • Background audio playback • Optimized for iPad Pro 120Hz displays Important Note BeatMeister plays audio files stored locally on your device. Tracks purchased from the iTunes Store (DRM-free) and imported files (MP3, WAV, M4A, AIFF) are fully supported. Tracks from Apple Music, Spotify, or other streaming services are protected by DRM and cannot be loaded or played. For the best experience, use your own DRM-free music library.
