VinylScratch turns your iPhone into a real scratch instrument. Load any audio sample and control it like a record — scratch, cut, loop, cue, and shape the sound with live effects — all with your fingers on the touchscreen. Whether you're a turntablist practicing cuts without decks, a producer sketching DJ-style arrangements, or a beatmaker who wants tactile sample control — VinylScratch gives you the physics, the effects, and the workflow to do it properly. Drop in a sample, feel the vinyl, twist the FX, hit record. VINYL PHYSICS ENGINE The scratch engine models real platter mechanics. Sound accelerates and decelerates the way a record actually does, with natural spin-down when you release. • Drag on the waveform to scratch — velocity and direction tracked sample-accurately • Three inertia modes: VINYL (natural spin-down), PAGE (instant stop), OFF • Adjustable sensitivity from ultra-fine to aggressive • Multitouch scratch support on iPad LIVE FX PAD A Kaoss Pad-style XY touch surface for real-time effects. Slide your finger to shape the sound — both axes control different parameters simultaneously. • Filter — LP/HP sweep and ISO (SP-404 style isolator) • Reverb — room, hall, plate and more • Delay — time, feedback, and LP cutoff control • Distortion — bit crush and lo-fi presets • FX1 & FX2 — two configurable effect slots with custom axis mapping • HOLD — lock the effect in place after lifting your finger • Glow trail visualization on the XY pad CUT & REV • CUT — hold to mute the signal, just like a crossfader kill • REV — flips playback direction • Crossfader strip for blend control CUE POINTS & LOOP • Two cue points: CUE A and CUE B — set, jump, clear • Loop IN/OUT with toggle — keeps the region when disabled • Full waveform view with overview strip TRANSPORT & RECORDING • Play / Pause with repeat mode • Record your scratch + FX session as WAV • Share or save directly from the app • Time display with millisecond precision AUv3 PLUGIN • Load VinylScratch as an instrument in GarageBand, AUM, Audiobus, or any AUv3 host • Full UI inside the host — scratch and effects included APPEARANCE • 15 color themes • Dark interface optimized for stage and studio PRO UNLOCK One-time purchase.
