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

About

FuzzWah

This audio effect plugin combines vintage fuzz and auto-wah effects, usable independently or in series. It offers unique sound shaping for instruments like guitars, synths, and vocals, with adjustable parameters for classic tones and modern experimentation.

Highlights
  • Independent or series fuzz and wah effects
  • Optional 'Vintage' fuzz mode
  • Skew option for gnarly fuzz tones
  • 4 selectable wah frequency ranges
  • Auto (envelope-follower) wah mode
  • Integrated noise gate

FuzzWah - Vintage Fuzz & Auto-Wah Plugin (AUv3) FuzzWah is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. Overview FuzzWah combines two classic effects in one plugin that can be used independently or in series. The fuzz box and wah-wah pedal were among the earliest guitar effects pedals and remain very popular to this day. While I think FuzzWah does work great with guitar, it can also produce interesting results on pretty much anything from drums, synths and even vocals. FuzzWah wasn't designed to be a clones or models of specific hardware effects, but it does draw inspiration from those classic units from the 1960's and 70's, then adds a few extra features. The fuzz section includes an optional "Vintage" mode for a rounder warmer tone, and a Skew option for dialling in that classic gnarly fuzz "ripping" sound. The wah section adds 4 selectable frequency ranges, and an "Auto" (envelope-follower) mode for funky filter auto-wah effects! FuzzWah also includes a simple "set it / forget it" noise gate to keep your signal nice and clean. Signal Chain & Amp Sims The order of signal processing is as follows: IN -> Noise Gate -> Wah -> Fuzz -> OUT You can drive the Fuzz section harder using the Wah Boost parameter. Much like in the real world, I think fuzzes sound best when going into slightly driven amps, rather than into something pristine and clean. Of course, that's entirely up to you, depending on the sound you want, but my personal favourite amp sim combo is FuzzWah going into ANALOGyAMP.

Verdict

The call

The clearest difference is price: FuzzWah at $1.99 against FAC Polyflo's $9.99. FuzzWah also leads on in-app purchases (none vs 3) and iOS requirement (12.0 vs 16.4). FAC Polyflo's advantage is rating (4.9 vs 4.5) and ratings volume (11 vs 2). On review sentiment, ads, monetization model and device support there is nothing between them.
