The iconic early-2000s “303” sampler sound now as a plugin.
Featuring 8 reverse-engineered effects and the legendary Vinyl Sim processor.
Available for macOS (AUv3/Standalone (VST/AAX to come)) and iOS.
Capture the gritty, coveted sound of the iconic early-2000s “303” phrase sampler right inside DAW or your favorite Audio Unit host. LP-33 Sim is a deeply researched audio unit plugin featuring 8 painstakingly reverse-engineered effects, headlined by the prized Vinyl Simulation processor.
Countless hours of A/B testing, spectral analysis, and machine-learning-assisted matching went into replicating the exact sonic character of Vinyl Sim and the other choice effects. From the aggressive, pumping compression that practically defines lo-fi hip-hop, to the warm wow-and-flutter and authentic dust and crackle, LP-33 Sim delivers the true gold standard of beatmaking.
LP-33 Sim takes several of the original effects further by adding full stereo widening for modern production workflows. Wrapped in a beautifully nostalgic interface that harks back to the golden era of hardware samplers, it brings the authentic warmth, quirk, and crunch that defined a generation — even if you’ve never touched the original hardware.
Key Features:
The Ultimate Vinyl Sim: A painstakingly faithful replication of the hardware’s legendary ducking compression, pitch flutter, crackling, and lo-fi grit.
8 Meticulously Replicated Effects: Vinyl Sim, Flanger, Chorus, Lo-Fi, Isolator, Pitch, FilterDrive, and Radio
Modern Stereo Enhancements: Classic mono effects expanded for wide, modern stereo fields, and AM/FM Radio simulation
ML-Assisted Precision: Exacting sonic matching built through rigorous spectral analysis and A/B listening tests.
Retro Interface: An intuitive, hardware-inspired UI that feels instantly familiar.
