For producers
who hear
differently.
Lucky777 wasn't built for everyone. It was built for the producer who opens a snare sample and immediately wonders what happens if you pitch it down 7 semitones, smear the transient, and run it through a granular engine. Now you don't have to wonder.
Drop any sample — 808, vocal chop, snare, foley — and pull the lever. Lucky777's granular engine slices it into grains and rebuilds something you've never heard. Bounce to WAV and it's in your session.
Scatter, density, spray, decay — every randomized roll produces a different textural outcome. Reverse grains, shift pitch, blend dry/wet. Export what you want. No two rolls are ever the same.
What's under
the hood.
Lucky777 atomizes your audio into microscopic grains and reconstructs it with randomized parameters: grain size (10ms–150ms), density, scatter, spray, and envelope decay. Every roll is statistically unique.
A precision stepped knob dials pitch in semitone increments from −12 to +12. Shift live during playback. The export engine uses linear interpolation to pitch-correct the full processed buffer before write-out.
Continuous mix knob from 0–100%. The dry path preserves your original signal at full fidelity. The wet path is pure granular texture. Blend precisely — subtle shimmer or full sonic destruction.
One click exports a 16-bit WAV at source sample rate — granulated, pitch-shifted, normalized. Everything runs in-browser. No server. No upload. Your audio never leaves your machine.
"They spent thousands on plugins
that do one thing.
This does it all — in a tab."
Three steps.
Infinite outcomes.
Drag any audio file onto Lucky777 or click to browse. WAV, MP3, FLAC — it decodes instantly in your browser. Your file stays on your machine the entire time.
Hit Roll. The granular engine fires with a new randomized set — grain size, density, scatter, spray, reverse. Dial pitch and wet/dry. Play. Roll again. Repeat until it hits.
When you hear the one — export. A pitch-corrected, normalized 16-bit WAV ready for your DAW, sampler, or wherever the session lives.
