ANALOGyDR Drum Synth (AUv3) ANALOGyDR is a virtual instrument plugin that can run standalone, or in any AU compatible host such as Logic Pro or GarageBand. Please note that the standalone version does not include a built-in keyboard - you need to connect a suitable MIDI device to play the synth. *** IMPORTANT - PLEASE READ *** ANALOGyDR is a single voice (monophonic) virtual analog synthesiser designed specifically for creating drum and percussion type sounds. Please note that it is not a pitched instrument for playing melodic lines, and does not include a rhythm pattern sequencer. To create a virtual drum kit with ANALOGyDR you need to load multiple instances on separate tracks in a DAW such as Logic or GarageBand and record MIDI notes into each track. Design Overview ANALOGyDR is a tribute to the now legendary vintage analog drum machines that used simple synthesis engines to create their sounds by combining basic oscillators and noise sources. ANALOGyDR has two variable pitch sine wave oscillators, along with white and pink noise generators, three filter types and an analog flavoured drive section. Despite the basic design, ANALOGyDR can create quite a wide variety of sonic textures, and the factory presets include a selection of percussion sounds inspired by the Roland CompuRhythm CR-78 (*), along with some interesting effects such as emulations of a cracking whip, a cardboard box and a mouse trap! The single voice architecture of ANALOGyDR is also useful in situations where you might want to add one or two additional percussion sounds to supplement your favourite drum machine app and gives you the flexibility to apply different effects processing to each ANALOGyDR track. Alternatively, use ANALOGyDR as a sound design tool to create your own unique percussion sounds that you can record and then load into your favourite sampler app. The iPad previews were created using multiple ANALOGyDR tracks in GarageBand, plus some reverb and echo from the built-in GarageBand effects.

• 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
