Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ANALOGyGR
This virtual analog synthesizer generates experimental sound design and atmospheric textures using a unique 'granalog' approach. It features eight polyphonic voices with multiple oscillators and adjustable grain parameters for dynamic, evolving sounds. 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

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.

• AUv3 plugin to modulate and sequence MIDI instruments and modular hardware • Outputs MIDI and analog CV simultaneously for integrated hybrid setups • Fully functional in software-only environments with full MIDI support • Converts LFOs, MIDI notes, pitch, and control changes into control voltages • Includes two LFO generators with random spline, cross-modulation and syncing • Integrated envelope follower to track audio input or sidechain signal • Six FLO(W) processors for combining and shaping signals with math and logic • Each FLO supports 18 inputs with individual polarity, divider and multiplier • Multi-out support, built-in waveform viewer, Audio FX, and MIDI FX • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Polyflo is an AUv3 plugin for modulating and sequencing MIDI instruments and modular gear via control voltage. It outputs MIDI and analog CV simultaneously, making it well-suited for hybrid setups that combine digital and analog equipment. The plugin includes two LFO generators offering 10 waveforms, including classic shapes and random spline, with support for cross-modulation and syncing. It also features an envelope follower that tracks audio FX input or an external sidechain. The generated signals, together with the host clock and MIDI input, are fed into six independent FLO(W) processors. These processors combine, shape, and route inputs using math operations, conditional logic, and comparators. Each FLO includes individual polarity, division, and multiplication controls, providing deep and flexible modulation that balances chaotic creativity with precise timing. Each FLO processor output is connected to its own output bus, enabling easy integration with hardware via DC-coupled audio interfaces like the Expert Sleepers ES-9. For simpler setups, FLO outputs can be routed to the stereo output. FAC Polyflo can also convert MIDI notes, pitch, and control changes into control voltages, making it a powerful MIDI-to-CV solution. If you prefer to work exclusively with software, the plugin runs smoothly in software-only environments with full MIDI support, making it equally suited for purely digital workflows. FAC Polyflo works as both an Audio Unit FX and MIDI FX, featuring a clean, touch-optimized interface with precise control and waveform visualization. It’s available as an AUv3 for iOS (iPad/iPhone), macOS, and Vision Pro, and requires a compatible AUv3 host app to run. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Polyflo.html
