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.

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.

Block diagram of the internal structure

This diagram shows all application modules and their connection. With this diagram, you can better understand the purpose of each control and how they can affect the signal.

The diagram shows one channel. All channels are identical. Signal flow in the channel passes from left to right, to the internal mixer buses (blue vertical lines). The feedback path is shown as red lines at the top.Using the group feedback path, you can build complex structures where several channels interact together in one feedback loop. The main element that defines the type of feedback loop is the input selector.

NoInputMixer (iOS/Mac/Audio unit) - Some details

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. NoInputMixer models an analog mixing console and effects rack in detail, providing the ability to make a huge number of feedback configurations with additional effects.

How does it work?

This text is taken from the descriptions of working with real mixers, but it is fully consistent with how this application works. In working with this application, you can rely on tutorials and demo videos that show real devices. The principles of operation and the result will be very similar, with the addition that this application offers much more options for creating patches and using effects.

There are two elements which allow no-input mixing to work. Firstly, we rely on noise, which is inherent in all audio equipment, to create feedback loops. Any audio equipment will generate noise due to the nature of its internal circuits and components, and that is what we need. We are taking advantage of the noise to make sounds which can be used creatively!

Secondly, we take advantage of mixer amplifiers. These amplifiers are designed to make weak signals stronger.

By taking this noise from the output of the mixer and feeding it back to the input and through amplifiers inside the mixer, we can amplify the noise, which is then output back into itself, amplified again, and so on.

While a single output into an input brings instant results, it is when multiple outputs and inputs are connected that the fun really begins. By adding effects to the signal chain between output and input, we can change the tones that are amplified and looped. This opens up endless possibilities for creating different sounds and experiment for as long as you wish to.

GlitchScaper as gated effect

Each GlitchScaper generator can act as a gated effect. To use this feature, select the "Stream" mode in the "Tone" section of the generator panel. In this mode, the external input of the app (input of the Audio unit effect) becomes the signal source for the generator. The signal is processed by the generator directly, without recording to the loop. The "Gate" parameter in the "Tone" section defines the envelope that controls the input signal level of the generator. Parameters "Frequency / Envelope", "Frequency / Range" and "Modulate the frequency / Type" are not used in this mode. Thus, the each active step of the internal sequencer opens the gate (run the envelope) and passes the input signal through the generator effects.

The input signal is cut into steps associated to an external rhythm (BPM) when this app is used as an Audio unit in a DAW or host app. That allows you to create ambient or glitch patterns match to the rhythm of a drum machine (or another instance of the GlitchScaper audio unit) from any external sources, regardless of its original rhythmic structure. Of course, for creating ambient patterns with long sequencer steps, it is best to use smooth source material with a not very noticeable rhythm. Using all six GlitchScaper generators as gated effects, you can create quite complex patterns. For example from internet radio.

Tip: In usual mode, the tone constructor (button "Make tone") uses an internal tone or noise as the generator signal source. To use the tone constructor for an external signal, set the generator to the "Stream" mode in the "Tone" section. In this mode, you can use the tone constructor for an external signal.

---

In the following example, the GlitchScaper processes the signal from the minimalistic streaming internet radio app Ström and creates a patterns that matches well with the rhythm of the drum machine app Elastic Drums. AUM app is used as the Audio unit / Inter-app audio host.

More details about this update:

• The new "Stream" mode for generators (in section "Generator - Tone") allows you to use this app as a six-channel gated effect. In this mode the generator uses a direct input stream as a signal source. This mode does not use the loop recorder and is similar to how gated effects work. The "Input" mode has been renamed to "Loop".
• A new button "Space: On, Continue, Off" has been added in the "Output" section to control the common reverb space and reverb reflections of each generator. With this button, you can turn off the overall reverb space and reverb reflections of the generators, for use external reverb / spatial effects as needed. This button also allows you to make reverb tails continue after the sequencer stops.
• Added the ability to create groups of presets. Now the list of presets can be organized more conveniently. You can create groups, move presets between groups and merge them. The "Favorites" group is created automatically when you make a preset a favorite. The "Factory" group contains all factory presets, and can be hidden in the settings.
• Added the ability to export and import presets and groups. You can save a preset or group to an external file, then import it into the app on another device.
• The "Solo" button has been added for all generators.
• Several new factory presets added.
• Improved work of generators in loop recording mode (the "Loop" mode).
• Sequencer control parameters exposed as MIDI and external parameters of Audio unit.
• Added a detailed description of the new modes to the built-in description of the app. Also available as a PDF file.
