Robot Butter is a creative AUv3 audio effect for compatible hosts on iOS & iPadOS. It blends animated modulation, adaptive reverb, tempo-aware movement, and digital texture into one fast, playable interface. At the core is the Robot engine, where Actuator, Viscosity, and Controller create the main motion and character of the signal. That signal then feeds Butter, an adaptive reverb stage designed to intelligently stay musical while responding to the effective movement of the Robot section. The result can move from focused width and pulse to washed ambience, strange motion, and unstable experimental color. The Chipset section extends the sound with a built-in assignable LFO matrix and a post-reverb System Bus reduction stage. Run the LFO freely in Hz or lock it to musical divisions for host-synced movement, then route it to key Robot or Butter controls for evolving motion. Add System Bus for subtle grain or push it harder for sharper, crushed digital edge. Robot Butter is designed to stay immediate. The interface gives you direct control over modulation, blend, depth, reverb shape, output mix, and motion timing without pushing you into a complicated modulation environment. A built-in user manual inside the standalone app includes overview pages, parameter explanations, quick-start guidance, glossary entries, MIDI notes, and troubleshooting help, with scrollable section pills that keep longer labels readable. Factory presets and user presets make it easy to jump from polished mix enhancement to stylized movement and aggressive sound design. Features: - Robot modulation engine with Actuator, Viscosity, Controller, and gain staging - Butter adaptive reverb with Churn, Emulsion, and Culture controls - Built-in LFO matrix with free or tempo-synced timing - Assignable LFO destinations across Robot and Butter parameters - System Bus sample-rate reduction stage for animated digital texture - Imaging modes including Mono, Wide, Ping, and Drift when stereo processing is available - Factory presets covering vocals, guitars, bass, keys, synths, drums, utility, and experimental categories - User preset save, recall, and delete support - Comprehensive built-in in-app user manual with quick-start, glossary, and troubleshooting sections - MIDI Learn, Host Learn support, and default CC mappings for hands-on control - Optional MIDI CC broadcast for compatible host-routing workflows - Host tempo sync with straight, dotted, and triplet divisions Use Robot Butter for vocal movement, guitar widening, synth pulse, drum bus animation, ambient wash design, or aggressive lo-fi modulation chains. It is built to move quickly from musical enhancement to animated destruction while keeping the workflow focused and playable.

Capture the gritty, coveted sound of the iconic early-2000s "303" phrase sampler right inside Logic, GarageBand, or your favorite Audio Unit host — or standalone on your iOS device. LP-33 Sim is a deeply researched audio unit plugin featuring 9 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. • 9 Meticulously Replicated Effects: Vinyl Sim, Flanger, Chorus, Lo-Fi, Isolator, Pitch, FilterDrive, and Radio (303 AM and a unique FM circuit with broadcast-like compression and widening) • Modern Stereo Enhancements: Classic mono effects expanded for wide, modern stereo fields • 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.
