AU EngineCore app effectively transforms any compatible multi-channel audio interface into a fully configurable digital mixer for live performance. Unlike traditional digital mixers, AU EngineCore offers a software-defined mixing environment, giving users complete control over routing, processing, and signal flow without hardware limitations. A key advantage is the ability to use studio-grade AUv3 plugins directly in live scenarios, enabling advanced processing and creative flexibility that typically requires dedicated studio setups. Built for precision, speed, reliability and real-time performance, AU EngineCore delivers ultra-low latency audio processing, flexible routing, and a clean, distraction-free interface. Key Features • Ultra-low latency audio engine for real-time performance • Advanced multi-bus routing with flexible signal flow • AU plugin support (inserts on channels, buses, and master) • Designed to work seamlessly with most multi-input audio interfaces • Stable performance even in complex live setups • Clean, classic interface optimized for fast operation • Real-time processing with no interruptions or audio artifacts in Live Mode • Multi-channel input and output support • Built for musicians, performers, and sound engineers Built for Live AU EngineCore is engineered to handle demanding live scenarios where stability and speed matter most. Every part of the engine is optimized to ensure smooth operation, even under heavy load. Flexible Audio Setup Connect your audio interface and build your mix the way you want: Route signals across multiple buses Insert AU effects anywhere in the chain Customize your workflow to meet your specific needs. Precision Without Distraction The interface is designed to stay out of your way, so you can focus on what matters: your sound. #nobodysbanda

About

DelayScaper

This audio effects plugin offers dual dynamic stereo delays that respond to input intensity and note spacing. It allows for experimental sound design, atmospheric textures, and even looping, with bonus effects like octave pitch-shifting and random reversing.

Highlights
  • Dual stereo delay modules
  • Dynamic parameter response to audio input
  • Host tempo syncable delay times
  • Max 8-second delay time
  • Octave Grains effect
  • Random Reverse effect
  • Envelope followers for modulation

DelayScaper is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. DelayScaper currently runs on iOS (iPad & iPhone) and macOS (Intel & Silicon) and is available as a Universal Purchase from the Apple App Store. Overview DelayScaper is a dual dynamic delay effect designed to produce inspiring, and sometimes very unpredictable results that literally responds dynamically to audio input. Playing an instrument through DelayScaper can be especially rewarding when you adjust your playing to what you’re hearing, because DelayScaper can be configured to constantly modify its parameters according to the intensity and spacing of your notes. It’s like having five extra pairs of hands twiddling knobs for you! At its core, DelayScaper comprises two identical stereo delay modules that can run in series or parallel. While it can cover “normal” delay duties, including host tempo syncable delay times, DelayScaper is really for those who like to experiment with sound, especially in the atmospheric and ambient realm. With a maximum delay time of 8 seconds, you can even use DelayScaper as an old-school “free looper” for “Frippertronics” type evolving soundscapes. DelayScaper also features two bonus “one knob FX” effects that are both original designs that complement the core delay processing: “Octave Grains” is a randomised and delayed pitch-shifting algorithm that sits somewhere between a pitch-shifted delay and granular shimmer effect. “Random Reverse” does what you might expect it to do, but often in an unexpected way! Both algorithms will grab random sections of the incoming audio, process it, then feed those into the main delay processing. The dynamics section is where DelayScaper comes to life, and includes dedicated envelope followers for both delays, which can then be used as a modulation source for up to 5 delay parameters for each delay. For example, you can modulate the mix level to create a “ducking delay”, or modulate tone so the delay repeats get brighter or darker depending on how hard or softly you play. A “cascade” feature sends the output of the first delay into the second, allowing you to fine-tune the balance between parallel and series mode.
