The latest release from independent developer Fred Anton Corvest offers a convenient way to control both MIDI-equipped instruments and CV-based modular gear. Available for the Mac, iPad, iPhone and Apple Vision Pro, Polyflo is capable of simultaneously transmitting MIDI and CV data, and comes packed with comprehensive modulation tools.
Polyflo features a pair of LFO generators that offer a choice of 10 waveforms and support cross-modulation and sync’ing, along with an envelope follower that’s capable of tracking either the input of an audio effects track or an external side-chain signal. The signals generated by the LFO and envelope follower, along with the plug-in’s host clock and MIDI input, are then routed to six FLO(W) processors. The processors are capable of combining, shaping and routing their input signals, with individual polarity, division and multiplication controls, providing deep and flexible modulation which the developer says “balances chaotic creativity with precise timing.”
Each FLO(W processor’s output is feeds its own dedicated bus, allowing users to easily integrate hardware instruments via an audio interface that offers DC-coupled outputs. For simpler setups, the output buses can be routed to the stereo output, and Polyflo can also convert MIDI Notes, Pitch and CC messages into control voltages. Those working entirely with software can still take advantage of Polyflo thanks to its full support of MIDI.
Key Features
- 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 side-chain 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.
Compatibility
Polyflo is supported on iPhones/iPads running iOS/iPad OS 16.4 or later, Macs running macOS 13.3 and above, and Apple Vision Pro devices running visionOS 1.0 or higher. It runs as an AUv3 plug-in.
