Neon is a lightweight digital audio editor and recording plugin compatible with any AUv3 host. It supports most major iOS file formats, and allows simple drag and drop between plugins. The editor allows you to import audio from a file or the system clipboard, as well as the ability to record incoming audio. As an editor it supports all the usual functionality you would expect as well as being able to edit samples on a per sample basis at extreme zoom levels. Neon also contains a number of built in effects that can be applied to the whole file or a selection. Effects can be previewed and tweaked prior to applying an effect. Neon can also be used as a clip launcher within an AUv3 Host, with the ability to remotely trigger one shot or looped samples. The Warp function can automatically adjust the tempo of a clip to the host tempo without affecting pitch. Neon also features a slicer which allows you to cut up a sample into multiple slices that can be played back via an incoming MIDI controller. ○ Record directly from other plugins. ○ Auto Start via trigger level supported. ○ Set maximum recording lengths in Beats / Seconds for perfect loops. ○ Drag and Drop Support between apps. ○ Drag and Drop selections to other apps. ○ Slicing and warping of audio. ○ Auto Sampler ○ AudioShare support. ○ Built in Effects. ○ Supports loading of external AUv3 effects (standalone mode). ○ Export to WAV, M4A, MP3 and FLAC formats. ○ Warp / Time Stretch functionality for syncing to host. ○ Host Sync. ○ Media Bay file manager for organising your clips. ○ Ability to set short name and colour in AUM. ○ Configurable MIDI Support for clip launching. ○ Supports iOS General Clipboard operations ○ Run multiple instances ○ LUFS measurement. Note: Neon imposes a 15min sample length limit on recordings due to it's memory restrictions as an AUv3 plugin.

• 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
