Devils Turntable vs The Remnant

WHAT DOES THAT SOUND LIKE BACKWARDS? For about thirty years people were convinced that rock and metal records had messages hidden inside them. Play the album in reverse and the devil speaks. It was nonsense, but it was very fun. Devils Turntable is a pocket-sized backmasking machine. Load a sound, hit SATANIZE, and hear it play in reverse while fire and smoke crawl up the face of the deck. HOW IT WORKS Record straight into the app with your microphone. Or import an audio file. Or drop in a video and the app pulls the audio right out of it. Then flip it. The record slows to a dead halt like you dragged your hand across the platter, then spins back up the other way. THE CONTROLS - SATANIZE — flips playback backward, then forward again - SPEED — bends pitch exactly like a real turntable. Slow it to a crawl or run it fast and chipmunked. - FIRE and SMOKE — two knobs that crank the atmosphere on the deck itself WHAT PEOPLE ACTUALLY USE IT FOR - Settling arguments. "That melody is just Happy Birthday backwards." Prove it in ten seconds. - Learning to speak backwards, which is a genuinely useful and genuinely stupid party skill. - Guitarists checking a reversed solo before they commit it to tape. - Testing your own voice memos for accidental demonic content. - Being the person at the party who says "wait — listen to this." HONEST ABOUT WHAT IT ISN'T This is a listening tool. It plays audio backwards. It does not export, edit, or save reversed files. If you need a reversed stem for a track, open your DAW like an adult. Devils Turntable is for checking, learning, and goofing off, and it does that faster than anything else on your phone. PRIVACY Nothing leaves your phone. No account, no analytics, no tracking, no ads, no data collection of any kind. Your recordings are yours and they stay on your device. No actual demons or poltergeists were summoned during the making of this app.

The Remnant is a feedback-matrix drone synthesizer. 8 FM voices modulate each other through an 8x8 routing grid. Signal circulates, persists, and transforms. You set conditions. The sound decides what to become. VOICES 8 FM oscillators with continuous waveform morphing: sine, triangle, saw, noise. Each voice has pitch, fine tune, morph, character (thin, normal with sub-octave, or wide unison), and level. Every voice can modulate every other voice through the matrix. FEEDBACK MATRIX The 8x8 grid is the core. Each cell controls how much one voice modulates another via FM. Diagonal cells create self-feedback. 7 topology presets configure the routing: Pairs, Ring, Star, Mesh, Chain, Random, and Custom. Each topology produces a fundamentally different timbre from the same voices. Edit individual cells by dragging. The synth auto-detects manual edits and switches to Custom. DRIFT Per-voice random pitch wandering. Each voice drifts independently with its own random LFO. Amount sets the deviation range. Rate controls the speed. Low settings: the sound breathes. High settings: voices pull apart into slow harmonic interference. EVOLVE Autonomous matrix mutation over time. Three modes: Wander drifts the matrix randomly. Breathe scales it in sinusoidal cycles. Decay dissolves the network into silence. Duration: 5 seconds to 10 minutes. Modulates on top of your settings, so knob positions are always respected. SNAPSHOTS 8 slots that capture the full sound state: all voice parameters, body/FX settings, drift, evolve, the full feedback matrix, topology, and XY pad positions. Long-press to save, tap to recall. Glide morphs every parameter simultaneously over up to 30 seconds. Transition between completely different sounds. XY PAD Two-axis touch controller. Each axis maps independently to one of 11 destinations: FM Density, Self-Feedback, Drift, Morph, Saturate, Air, Body Decay, Pitch Spread, Tension, Atmosphere, Chaos. Snap-to-center returns on release. Per-sample modulation for FM targets. PLAY MODE Transforms the drone into a touch instrument. 8 velocity-sensitive pads gate individual voices through attack/release envelopes. Expression modes: Volume, Filter (2-pole lowpass), or Morph (pad Y overrides waveform). Pitch bend on pad X. Per-voice latch. Latch All for quick voice management. MIDI input on C4 through G4. RESONANT BODY Physical resonance filter with 4 modes: Chamber, Cave, Metal, Void. Turn Decay to maximum and the body self-oscillates, becoming a sound source on its own. EFFECTS Saturate adds tanh waveshaping from subtle warmth to full destruction. Space spreads voices across the stereo field. Air adds reverb. HARMONY Free or scale-quantized pitch. 13 scales including Major, Minor, Dorian, Pentatonic, Blues, and more. Root note and reference tuning (432/440/442/444 Hz) configurable. 25 factory presets across 7 categories. Save your own. 2x oversampling for alias-free FM. Double-precision phase accumulators. Works as AUv3 in GarageBand, AUM, Logic Pro, and any AUv3-compatible host. Runs standalone on iPhone and iPad. Also available as VST3, AU, and CLAP on desktop.
