No-Input Mixing is an experimental technique for creating a wide range of amazing, otherworldly electronic sounds by feeding the mixer output back to the input, thereby making a feedback loop. This application models an analog mixing console and effects rack in detail, providing the ability to make a huge number of feedback configurations with additional effects. By using this technique in the creative process, the sound designer can explore many different and special ways to create sound. Unsettling soundscapes perfect for sci-fi, dystopian and horror projects, like strange noises, disrupted signals, broken communication, buzzing drones, faulty machinery, futuristic tech sounds, and glitchy elements are some results of the No-Input Mixing technique. The downside of this technique, which can scare off beginners, is extreme unpredictability and instability, when the movement of any knob on the mixer can dramatically change the sound in the most unexpected way. But at the same time, this discover an endless space of experimentation and inspiration when creating new and unique sounds or live performance. In addition, a large set of ready-to-use drone and noise presets with a parameter randomizer provide a great point for quickly getting started with this application. NoInputMixer consists of a seven-channel mixer and an effects rack with eight slots. Each effect slot can be configured as an insert effect for a mixer channel or used with two send/return buses. Effects has an option for hi-res or lo-fi sound processing. Each mixer channel has its own algorithmic generator of different types of noise, which can be added to the feedback signal or used separately. The input selector switches between multiple points in the signal path to make different types of feedback loops or can be switched to an external input for any channel to use it as an effect processor. Also this application provides several additional options not found in usual mixers, such as preamp tube type and mode selection, op-amp type selection, adjustment of overload protection circuit, and other features that greatly expand the possibilities for experimenting with sound. The user interface can be presented in the form of a classic mixer, or in the form of complete control of a single channel. NoInputMixer is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). NoInputMixer works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus. On MacOS, NoInputMixer can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. NoInputMixer has a built-in detailed description of all parameters also available as PDF file on the application website.
