Ratshack Reverb is a detailed model of that classic of classics, the Realistic Electronic Reverb. Now, you can have the sound of everyone's first analog delay unit, without ever having to change batteries! As anyone who has owned this unit (which is just about everyone...) knows, it was actually an analog delay, not a reverb at all, and we've done our best to exactly replicate the sound and quirks of the original. We've even modeled the distortion that occurs by running a line signal in to the mic inputs. Features » Accurate analog "bucket-brigade" style delay model. Change the delay time, and the signal pitches accordingly. » Both mic and line inputs modeled, for overdriving the delay section if desired. » XML-based cross-platform preset manager, with copy and paste. (You can even move presets between the iOS version and the desktop version with Handoff.) » Entirely vector-based resizable high-resolution user interface » Both IAA and AUv3 versions included.

GRFX is a powerful and creative granular effects processor that turns ordinary audio into extraordinary sonic landscapes. Slice your sound into grains and reshape them into evolving textures, shimmering chords, rhythmic glitches, haunting drones, and more. At the heart of GRFX is the Harmonic Triangle – an intuitive 3-way pitch controller that lets you morph simple tones into lush pads, arpeggiated patterns, or abstract gestures. Whether you’re aiming for organic soundscapes or synchronized stutters, GRFX gives you precise control over the flow of grains and modulation. Build complexity with four self-modulating LFOs, a multi-effect chain with probabilistic routing, and an elegant drag-and-drop modulation system. Shape your sound, modulate nearly every parameter, and sculpt immersive audio transformations in real time. Key Features: - Granular engine for creating textures, rhythms, chords, glitches, drones, ambiences, and more - Harmonic Triangle for 3-way pitch control, detuning, and microtonality - Built-in Chord Selector with 32 triads for instant harmonic richness - Grain envelope shaping for plucky, smooth, or abrupt grains - Buffer size, division, sync, and freeze controls - Rhythmic synchronization for tempo-synced effects and patterns - 4 LFOs with self-modulation and drag-and-drop assignment - Modulation panel & view mode for streamlined modulation management - 2 Multi-Effect slots (Filter, Distortion, Delay, Peak EQ, Chorus, Phaser, Bitcrusher, Reverb) with probability-based routing - Dedicated Send FX with Delay and Reverb in series or parallel mode - Flexible mixer section for sculpting wet/dry balance and routing AUv3 Audio Unit plugin – requires an AUv3-compatible host app such as Logic Pro, GarageBand, AUM, or Cubasis.
