• 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

MathRonome is a polyrhythmic visual metronome designed for musicians, music teachers, and students. Watch two independent rhythms orbit in sync, hear every beat, and build your rhythmic vocabulary from simple time-keeping to complex polyrhythms. FEATURES • Two independent metronomes (M1 & M2) with visual ring animation • Subdivisions from 2 to 5 (free) or 2 to 32 (Pro) • Common Pulse — hear and see the pulse both layers share, with the moments they meet accented on the dial • Divisible Beats — long-press any beat to split it into equal sub-beats (triplets, quintuplets, sixteenths) and toggle each one • Toggle individual beats on/off to create custom patterns • Randomize beat patterns for sight-reading practice • 1 sound preset (free) or 4 presets: Percussion, Drums, Marimba, Piano (Pro) • Adjustable tempo from 1 to 120 RPM • Independent volume and mute controls per metronome • Background audio — keep practicing while using other apps • Bluetooth audio latency compensation slider • Interactive tutorial with step-by-step guidance • Works on iPhone and iPad PRO UPGRADE ($2.99, one-time) • Full subdivision range: 2 to 32 • All 4 sound presets • Swap M1 and M2 subdivisions instantly • Switch Mode: automatically alternate between metronomes Perfect for: • Music students learning polyrhythms (3:4, 5:7, etc.) • Teachers demonstrating rhythm concepts visually • Drummers and percussionists building independence • Any musician wanting to strengthen their internal clock No subscription. No ads. One optional upgrade. New in 1.2: Common Pulse. Switch on the pulse the two layers share and watch the polyrhythm resolve — a subtle shaker marks the smallest beat both rhythms have in common, dots around the dial show where each layer falls, and the moments where they meet ring out a little louder and brighter. The clearest way yet to hear, and see, two rhythms lock together.
