About

Bit Maestro

This audio effect plugin allows manipulation of sound at the individual bit level, creating unique digital distortions. It offers advanced control over bit evaluation order and includes filters, a delay, and modulation for enhanced sound design.

Highlights
  • Individual bit manipulation
  • Bit evaluation order rearrangement
  • Three filter types (LP, LS, HS)
  • Integrated delay line
  • Modulation panel for evolving sound
  • AUv3, MIDI, IAA, and Audiobus support

Bit Maestro is an AUv3 bit crusher that goes beyond regular bit rate reduction, allowing you to affect and manipulate your sound at the individual bit level. Taking inspiration from the legendary ‘OTO Biscuit’ it enables you to selectively mute or invert individual bits in your audio signal. As it does this it creates distortions in your waveform, introducing a wide range of harmonics. Bit Maestro pushes this concept even further, allowing you for the first time to even rearrange the order in which the bits are evaluated, reassigning their value and giving rise to waveform distortions not previously seen in any distortion module. This sound can be further enhanced in a number of ways. - Three filters are available (low pass, low shelf, high shelf) which can be used to tame or enhance the aggressiveness of the sound. - A delay line to inject a different groove into a bar or provide a basis for interesting mod effects. - A modulation panel to continually evolve your sound and introduce further aliasing effects. The end result is a plugin that can introduce huge depth and power to your sound. One that offers you the nuanced control to design your perfect digital distortion, ranging from subtle warbling to huge crushing sounds that can transform any drum or bass line. Supports: - AUv3 - MIDI control - Inter-app Audio - Audiobus

• 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
