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.

OpenDeck DJ

OpenDeck DJ turns your iPhone or iPad into a single-deck DJ player modeled on a professional club media player: a large jog wheel with a spinning platter display, a tempo fader, transport controls, a zoomable waveform, hot cues, beat loops, and automatic BPM and beat-grid analysis. BRING YOUR OWN MUSIC Drop MP3, AAC/M4A, WAV, AIFF, FLAC or OGG files into the OpenDeck DJ folder in the Files app (On My iPhone / On My iPad → OpenDeck DJ), or from a Mac via Finder, and browse them from the deck's BROWSE screen. A demo track is included so you can try everything straight away. ON IPHONE AND IPAD On an iPad the whole deck is on one screen. On an iPhone it is two landscape pages: the player's screen, and the controls (jog wheel, tempo fader, transport, loops) with the beat meter and BPM in view. Flip between them with the page button or a two-finger swipe. PLAY ALONGSIDE THE CLUB STANDARD OpenDeck DJ speaks Pro DJ Link. On a local network it appears as another player next to CDJ/XDJ decks: it can follow the shared tempo and beat grid with SYNC, or take MASTER and lead. It also shares its music: other players list it in their LINK menu and can browse and load its tracks, with BPM, beat grid and waveforms. Link hardware is optional — the app is a complete standalone player on its own. FEATURES • Jog wheel with vinyl (scratch) and nudge modes and a live centre display • Tempo fader with ±6 / ±10 / ±16 / WIDE ranges and MASTER TEMPO key lock • CUE with AUTO CUE, hot cues A–D, memory points, beat loops from 1/2 to 16 and SLIP • Zoomable waveform with beat and bar markers, full-track overview and needle search • Automatic BPM and beat-grid analysis, with GRID ADJUST (snap, shift, reset) • QUANTIZE so cues and loops land on the beat • Pro DJ Link: SYNC, MASTER, beat and phase meter, LINK browsing of other players' media, and serving your own to them • TAG LIST, track INFO and a UTILITY menu (player number, tempo range, quantize, auto-cue level) • Runs entirely on-device: no account, no sign-in, no analytics OpenDeck DJ is an independent open-source project.
