• Exospheric stereo reverb with ultra low latency pitch shifting • Amazingly lush, dreamy and beautiful • Shimmer kind effect, harmonizer • Unique feedback processor and fine tuning of the All-Pass delays • High-pass filter and stereo width input controls, separate Dry/Wet outputs • Sidechain input to duck the reverb • Multiple outputs, extra output bus to route the feedback signal to your own fxs • Advanced Responsive Design, portrait and landscape views • iOS Audio Unit V3 - Universal (iPad/iPhone) Designed for ethereal lush sound textures and dreamy space reflection, FAC Alteza is the perfect solution to bring your instruments to heaven in no time. Thanks to a powerful feedback section containing, inter alia, two pitch shifters, the unit is able to deliver the very typical "Shimmer" sound kind effect very much prized by musicians that are making ambient music, or any kind of music that needs to be carried by a fabulous angelic evolving choir section. FAC Alteza is definitely not "another shimmer reverb..." effect because it comes with additional parameters that make it very versatile. A particular attention to each part of the signal path was necessary to reach this level of high-end quality. Here some features that make FAC Alteza an outstanding unit: • the input signal is not monoized by default, a knob allows to control the width of the input stereo image before reaching the reverb • the topology of the effect, based upon a series of All-Pass delays, allows to control the intrasec characteristics of the reverberation • the number of All-Pass delays per stage and the echo density are alterable in the main section and in the feedback section • two ultra low latency pitch shifters deliver progressive pitch-shifting of the reverberation tail or the input signal • the feedback section contains a blend knob to control how much of the original signal is mixed with the feedback reverb • the wet signal can be ducked by an external signal provided by the host - AuV3 and Standalone App - To use the sidechain and/or to output the additional feedback signal, you need a host able to provide to the AuV3 an input bus and an additional output bus.

Designed for real-time performance and manipulation, it integrates with MIDI devices and hosts.
- Eight-voice polyphonic virtual analog synth
- Granular-inspired oscillator rendering
- Adjustable grain shape and length
- Randomized oscillator and grain parameters
- MIDI CC and polyphonic aftertouch support
- Real-time performance manipulation
- AUv3 plugin and standalone operation

ANALOGyGR Granalog Synth (AUv3) ANALOGyGR is a virtual instrument plugin that can run standalone, or in any AU compatible host such as Logic Pro or GarageBand. Please note that the standalone version does not include a built-in keyboard - you need to connect a suitable MIDI device to play the synth. What's a "granalog" synth? It's granular... but (probably) not as you know it. ANALOGyGR (analog-ee gee are) is not a granular synth in the traditional sense, but it does borrow some ideas and terminology from granular synthesis. Please note that ANALOGyGR is not a file-based audio effects processor that allows you to load your own samples, and this is what makes it different, possibly even unique! At its heart, ANALOGyGR is an eight voice polyphonic virtual analog synth with oscillators that are rendered as "grains". While ANALOGyGR can get close to sounding like a "normal" synth, it's really aimed at people who prefer more experimental type sound design and atmospheric textures. For traditional analog sounds, I'd ask you to also take a look at the popular ANALOGyXS (poly) and ANALOGyX1 (mono) synths as all three cover slightly different sonic territory. Design Overview Each of the 8 voices in ANALOGyGR have 3 dedicated grain oscillators each (saw, triangle and square waveforms), and these 24 oscillators are used to generate grains of varying shape (saw, ramp and triangle envelopes) and variable length (50ms to 10 seconds). The oscillator and grain shape can also be randomly selected on each grain cycle for some really interesting dynamic textures, and grains are also randomly spread in the stereo field. ANALOGyGR also has a noise generator that can be applied to the main amplitude ASR envelope, or at the grain level. Grain notes can be pitched up or down an octave on alternate cycles or randomly per voice, and can also glide from one note to the next which can make even the simplest chord sound much more intriguing! ANALOGyGR also shares many of the "under the hood" features introduced in ANALOGyXS and ANALOGyX1 which can result is some very complex, evolving and dramatic sounds for a relatively small synth with just 16 parameters. Speaking of which... ANALOGyGR has been designed very much as a performance-based instrument to be played and manipulated in real-time. To facilitate this, all of the instrument parameters are controllable via dedicated MIDI CCs from your keyboard or another MIDI generator plugin. ANALOGyGR can also respond to channel and polyphonic aftertouch pressure MIDI messages for an enhanced and expressive playing experience. As the sounds of ANALOGyGR typically tend to evolve over time, it is perhaps better suited to sustained note passages and sparse / simple chord voicings combined with a dynamic playing style. Please note that while ANALOGyGR has been designed to be CPU-friendly, if you want to take advantage of the extended MIDI capabilities such as polyphonic aftertouch and parameter modulation, a fairly up to date hardware setup is recommended.

Verdict
The clearest difference is in-app purchases: ANALOGyGR at none against FAC Alteza's 3. ANALOGyGR also leads on price ($2.99 vs $9.99) and update cadence (fortnightly vs every 5 months). FAC Alteza's advantage is rating (4.9 vs 4.7) and ratings volume (81 vs 10). On review sentiment, ads, monetization model and device support there is nothing between them.

FAC Alteza costs $9.99 and ANALOGyGR $2.99 up front. FAC Alteza sells 3 one-off in-app purchases. ANALOGyGR asks for nothing beyond the download.
FAC Alteza holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: FAC Alteza has 81 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 94% of FAC Alteza's written reviews are positive against 100% of ANALOGyGR's, so the app with the better star average is not the one people write more warmly about.
FAC Alteza ships an update every 5 months, ANALOGyGR fortnightly. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
