What Sets DJ Pro Apart
Six core features that make DeviceLab DJ Pro a professional-grade mobile DJ platform.
AI Stem Separation
TensorFlow Lite-powered real-time stem isolation splits any track into vocals, drums, bass, and other instruments. Mute, solo, or remix individual elements live during your set for creative transitions and mashups.
4-Deck Performance Engine
Professional mixing console with up to 4 simultaneous decks, motorized jog wheels with touch sensitivity, independent 3-band EQ, channel faders, and a precision crossfader with adjustable curve settings.
BPM & Key Detection
Advanced audio analysis engine automatically detects BPM with sub-decimal accuracy and identifies musical key using chromagram analysis. Harmonic mixing suggestions ensure your transitions are always in key.
MIDI Controller Support
Full MIDI mapping with learn mode — tap any control on your physical DJ controller and assign it instantly. Community-shared mappings for popular controllers like Pioneer DDJ, Numark, and Native Instruments.
USB Audio Routing
Professional audio output with USB audio class support, multi-output routing for headphone cueing and main output, and a low-latency audio engine optimized for real-time performance with minimal buffer.
Mix Recording Studio
Record your entire set in high-quality audio with waveform visualization. Edit cue points, trim recordings, and export in multiple formats. Perfect for sharing mixes or reviewing your performance.
Technical Specifications
Built with Kotlin and Jetpack Compose, powered by TensorFlow Lite for AI stem separation, Media3 for audio playback, and Oboe for low-latency audio processing.
