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.

Parrot
This app creates rhythmic patterns by sampling and repeating small slices of incoming audio. It offers extensive control over loop length, pitch, variation, and dynamics to generate unique, evolving textures for music production.
- Rhythmic pattern generation
- Audio sampling and looping
- Adjustable loop length and pitch
- Dynamic variation control
- DAW syncing
- Free-run generative mode

Unpredictables have more fun From subtle beat variation or harmonic accents to glitchy mayhem, Parrot adds something unique and interesting to anything that you feed it with. This effect will help ignite your next dance-floor hit or add that extra je ne sais quoi of flavour to your mix. Whatever you feed the Parrot, it won’t let you down! Parrot creates rhythmic patterns by sampling small slices of incoming audio, and repeating it in a sequenced loop. With control over loop length, pitch, variation, dynamics and filtering, the result can easily take off in any direction you want. Each slice becomes part of a loop that keeps reshaping itself as you adjust parameters, making patterns that feel alive. The sequencer reacts strongly to small changes, so even minor tweaks can introduce new pulses, stutters or harmonic shifts. Parrot can hold on to a steady rhythm, but it’s just as comfortable dissolving into broken loops and glitchy textures that evolve over time. When synced to your DAW it slots neatly into structured productions, while the free‑run mode opens up a more exploratory, generative side. The smallest change can create a new pattern, almost like turning a kaleidoscope and watching the pieces fall into a fresh formation. As the loop repeats, the interplay between timing, pitch and modulation build a sense of movement that keeps the rhythm from feeling static. Filtering can push the sound forward or bury it in grainy motion, and dynamic shaping helps each step take on its own character. Over longer sessions, patterns can morph in ways that feel unexpected yet connected to the original source, gradually forming textures that sit somewhere between groove and ambience. From gentle movement to complete fragmentation, Parrot acts as a creative companion that constantly feeds new rhythmic ideas back to you, encouraging ongoing exploration and rewarding every small adjustment with a new possibility.
