About

lfoch

This app generates complex LFO waveforms with multiple outputs for creating "chase" effects. It offers two LFO generators with phase modulation, adjustable suboscillators, and waveform morphing. It can output MIDI control change values and sync to tempo.

Highlights
  • Dual LFO generators with phase/ring modulation
  • Suboscillator modulation with waveform morphing
  • Adjustable waveform rate, type, and range
  • Output 1-16 MIDI control change values
  • Tempo synchronization and AUv3 MIDI Effect support
  • Two modes: 'perform' and 'edit'
  • Randomize parameter values

lfoch is an experimental LFO generator that can create "chase"-like effect with multiple outputs from a single complex waveform It features: - 2 LFO generators with phase modulation / ring modulation: - Each LFO generators contains 2 suboscillators; one suboscillator modulates phase of another - For each suboscillator you can set waveform rate, waveform type (with smooth morph between sine, triangle, sawtooth and square waveforms), nonlinear curve (for overdrive-like effect) and minimum/maximum range - The result waveform is a multiplication of two generated LFO waveforms - You can use 1..16 points from this waveform to output as MIDI control change values - You can toggle the "playback" (phase change) of each generator with I/II buttons - You can randomise parameter values with "dice" buttons - App has two modes for live usage - 'perform' mode has larger waveform view and some selected sliders (if any) - 'edit' mode contains all controls on one screen - Each generator can be synchronized to tempo. In this mode the "speed" value runs from 4 quarter forward to 4 quarter backwards speed, the fastest value in this mode is 1/32 - When running inside AUv3 host the app uses host's transport. - "free mode" setting allows you not to follow the host transport lfoch is a standalone app and an AUv3 MIDI Effect. AUv3 effect supports parameter automation and preset saving inside host. Standalone version currently does not output MIDI in background mode.Note for AUM users:This application starts with 16 control change outputs from CC 0 to 15 on MIDI channel 1. AUM has default mapping of the CC #7 (volume) for each channel. Please keep this in mind when setting it up together.

• 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

Verdict

The call

The clearest difference is review sentiment: FAC Polyflo at 100% against lfoch's 50%. FAC Polyflo also leads on rating (4.9 vs 4.4). lfoch's advantage is in-app purchases (none vs 3) and price ($3.99 vs $9.99). On ratings volume, ads, monetization model and device support there is nothing between them.
