GrainProc is a real-time granular synthesizer with which you can create new sounds and musical textures by affecting your voice, your instrument, or any input from AudioBus. 2 grain engines run in parallel, allowing you to layer two sounds and create rich textures, even as a solo performer! Features: • 2 Granular synthesizers running in parallel • Waveform representation of the sound allowing you to touch where you want the sound source to be • Sliders to control dry volume, wet volume, feedback level, and grain density • Visual level monitors of the dry, wet and feedback levels • Simple enough to be used with your feet! We discourage using your device with your feet, though it has been used that way for public performances!

Read full description

Quarked is a high-performance granular synthesizer designed for precision sound design. Built around a native C-based audio engine, it prioritizes low-latency manipulation and a functional workflow that stays out of your way.

Quarked treats sound as a physical material, allowing you to zoom, slice, and re-texture with tactile, high-precision controls. The Engine: Granular Core: Independent control over grain size, density, position, and scan speed. Performance First: A native audio backend ensures smooth parameter interpolation without artifacts. Note-Level ADSR: Professional-grade envelope shaping with exponential curves for natural release. The Workflow Precision Ruler: Navigate waveforms with high-resolution sliders designed for micro-adjustments. Technical Aesthetic: A flat, distraction-free interface inspired by modern studio hardware. Dynamic FX Chain: A reorderable signal path featuring Delay, Reverb, Shimmer, and a 3-band technical EQ.
