dSL1200 — Digital SL-1200 A professional DJ turntable simulator and music player for iPhone — a faithful real-time emulation of the most-used direct-drive deck in DJ history. Every part of the deck modeled in 3D, most touch-controllable. THE DECK, REBORN For nearly fifty years, one direct-drive turntable has been the de-facto industry standard in clubs, hip-hop, dance, and bedroom studios across the world. dSL1200 captures that deck — its motor, its slipmat, its quartz-locked strobe, its long-throw pitch fader, its tonearm tracking — as a working real-time simulation, not a skin or a sample player. REAL TOUCH, REAL SCRATCH Touch the vinyl and the platter responds the way a real one does. The motor keeps spinning underneath while you scratch, the slipmat couples back when you let go, and the audio rate follows your finger through every back-cue, body-trick rub, and crab. QUARTZ-LOCKED STROBE The multi-dot rim ring locks at exactly 33⅓ and 45 RPM through honest motor-rate-driven strobe physics. Pitch off center and the dots drift; lock to nominal and they freeze — the same visual feedback DJs have used to beat-match by eye for half a century. ACCURATE PITCH RANGE Faithful to the original long-throw pitch fader, with ±8% range, a center-detent snap, and strobe drift independent of motor rate. Beat-match by eye exactly the way the deck was designed for. YOUR MUSIC, ON THE DECK Plays MP3, FLAC, WAV, AIFF, and Apple Lossless files from your iOS Music library — any DRM-free track you've imported, ripped, or purchased. (DRM-protected Apple Music subscription streams cannot be played.) The vinyl label is generated from each track's metadata, with title and artist printed on the LP. LOOP PLAY FOR BREAKS Toggle loop mode and the track wraps with zero-sample-gap continuity — perfect for chopping b-boy breaks, drum loops, and battle samples. Cue points and back-cues across the loop boundary work transparently. AUv3 EFFECT RACK Load any installed Audio Unit Extension into a wet/dry parallel mix. Reverb, delay, filters, EQ, distortion — any AUv3 plugin you have on the device works. 3D TONEARM Drag the arm to cue, tap the cue lever to lift and drop, and watch it sweep from outer rim to inner spindle in real time with the audio playhead. The anti-skating dial, height adjustment, and counterweight are visually modeled on the 3D deck for fidelity to the original (not user-adjustable in this version). AUTHENTIC LIGHTING The pop-up inspection lamp lifts and lights with a warm bulb when toggled. A red strobe LED throws a sharp glowing arc across the platter rim — the same flashing red light that makes a working deck look alive in low-light club environments. 120 Hz METAL RENDERER Native 120 Hz on ProMotion devices, 60 Hz everywhere else, with PBR lighting, real-time reflections, vinyl groove geometry, and adaptive touch-density compensation so scratching feels identical regardless of refresh rate. ENGINEERED FOR DETAIL - End-to-end touch-to-audio response under 6 ms - Adaptive high-resolution resampler tuned for scratching - Streaming + ring buffer for tracks of any length - Slipmat physics, not state-machine fakery dSL1200 is an independent simulation product. It is not affiliated with, endorsed by, or sponsored by any manufacturer of physical turntable hardware. Any visual or behavioral resemblance to professional DJ equipment is offered as faithful artistic homage to a category of product that has shaped DJ culture for decades.
