FAC Gravity

Features
Read full description

FAC Gravity AUv3 Plugin is a frequency shifter for creating Barberpole and Shepard style glissandos, spectral illusions, stereo rotation, chorusing, phasing, evolving echoes, infinite cosmic spaces, and all the combinations you’ll make. The plugin gives you two ways to process the audio source. In Stereo mode, each channel is shifted independently, with a Ratio control determining how closely their frequency shifts align. In Mono mode, FAC Gravity extends the internal quadrature processing to create a wide stereo image from the mono source. The frequency shift can move up or down, from subtle to more extreme spectral transformations. You can set the amount in Hz for classic Bode-style frequency shifting, make it follow your host tempo for rhythmic patterns, or even control it from MIDI notes for a more hands-on approach. A new dimension appears when you let the shifter feed back into itself with Spiral, a customizable loop with delay, blur, filtering, and different characters that shape how the sound circles, smears, interacts, and evolves over time. The result can range from bubbling textures to infinite sustained tones and noisy analog self-oscillation. Each character takes the feedback somewhere different. To dive deeper into new sonic dimensions, FAC Gravity comes with its own modulation module. The LFO, envelope follower, and flexible modulation matrix let you animate most parameters, from subtle evolving movements to complex, rhythmically reactive changes. You can even make the stereo field animate and rotate continuously by making the Width, Phase, and Pan parameters spin! You can shape the effect further by blending the processed signal with the original, while the optional limiter keeps the most extreme combinations in check. • Barberpole glissandos, spectral illusions, rotating stereo, evolving echoes • Dual Frequency Shifting, or Mono Shifting with Quadrature Stereo Widening • Organic Spiral Loop, from gentle feedback to pure analog self-oscillation • Integrated delay, diffusion blur, and independent low/high filtering • Modulation matrix, multi-source envelope follower • LFO with classic waveforms and random spline • Spinning modulation to rotate and animate the stereo field • Tempo-synced or MIDI-driven Frequency Shift, LFO, and Delay • Dry/Wet mix, optional limiting, and goniometer visualization • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro The documentation is available at fredantoncorvest.com/FAC_Gravity.html This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them

Construct evolving sequences. The creative experience of using a constrained hardware system rather than the lazy freedom of just being able to “add another module”. ThreeTuring lays out everything in front of you without the need to keep going back to the manual. No menu diving, no alternative pages and easy to pick up if you haven’t used it for a few weeks or months. Having fun making music. ThreeTuring consists of a dual oscillator monosynth, a clock module for generating trigger patterns alongside a collection of generative modules encompassing a range of modular generative techniques including a turing machine, random generators, LFOs, envelope generators, a quantiser, a note accent and a set of effects modules. Pretty much every control can be modulated via the nine slot modmatrix, including the modulation settings themselves.

Verdict

The call

The clearest difference is in-app purchases: ThreeTuring at none against FAC Gravity's 3. ThreeTuring also leads on iOS requirement (15.0 vs 17.0). FAC Gravity's advantage is ratings volume (6 vs 1). On price, rating, ads and device support there is nothing between them.
