Dubstation has been a fixture in dub, electronic, and pop production for nearly twenty years. It emulates the analog bucket-brigade delays of the 1970s and 80s, with their pitch-bending, warmth, and gradual high-frequency loss intact, then adds things those circuits could never do: true stereo dual-time delays, ping-pong, a stereo LFO, and a clean digital looper with overdub and reverse. Sound and Character The bucket-brigade model is the real thing: the high-cut frequency tightens as delay time gets longer, exactly like the original hardware. A low-cut filter trims the bass for the thin echoes of early Jamaican dub. A saturation stage on the feedback path adds analog-style breakup as repeats stack up, and the LFO modulates delay time for chorus, flange, and pitch swoops. Looper and Reverse The LOOP switch turns Dubstation into a clean digital looper that holds the buffer indefinitely and accepts overdubs. This is different from cranking the feedback, which degrades and distorts the signal over time. The REVERSE switch flips the delay memory backwards, and combined with the looper produces reverse loops that hold their fidelity indefinitely.

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. Standalone version included.
