Soniface Pro Features - Unlimited instruments - Pattern mode to create unlimited scenes - Airplay Visual Mode with HDMI Video-Outputsfor performance & VJing - Unlimited internal audio recording in .wav - By purchasing the Pro, you are directly supporting development Key Features Creative space to explore sound, music and geometric visuals Experiment with audio and visual objects and create your own scenes Operate controllers and play instruments via multitouch Motion interface to control instruments and parameters through gestures, movements and dance Cross-platform compatibility of project files Simple design for mobile devices, complex (regular) design for tablets and desktops Advanced in-app guide, FAQ & help function in English and German Instruments Gridsynth - A generative, visual synthesizer for drones and melodies incl. sequencer & arpeggiator Rhythm sequencer for sample- and synth-based basses and drums Spatial & granular soundscape sampler incl. mic input, sample library and file integration Key interface for cross-instrument tonality incl. progression sequencer Interactive LivePad and keyboard for Gridsynth, Bass & Sampler Automation & Connectivity Advanced controller automation incl. multi-touch editor, body tracking interface MIDI input and output Master FX and Ableton Link Normal mouse and keyboard support Audiobus & Inter-App Audio (experimental support) The Pro version represents all capabilities of our yearlong development in terms of a creative progress. The Pattern Mode is the essential feature in the context of musical and performative application. Therefore you have a simple, editable list of Patterns on the main screen. The Pattern Mode enables to build scenes with several instruments and samplers, each with different main settings like tempo, pitch, main EQ, sequence length as well as motion tracking connections. The additional Visual Interface gives you the possibility to design a whole new look for each scene. The visual corresponds to the sound as well as the motion interaction and main FX. In relation to your device it supports up to 3 display outputs with separate content. Soniface Pro combines a modular concept with spatial audio abilities. This offers new approaches to audiovisual performances and interactive installations. The desktop version supports surround sound output up to 7.1 speakers. The objects on the display become positioned within the XY field of the surround room. Soniface Pro does not refer to pro audio but allows you to use all facets of the software. As reference, you will find videos and music of our works (Ectoplastic) which were completely made with it, like multichannel audiovisual performances as will as our musical releases. There are a lot of pro features on our list and we are looking forward for the next update. Don't hesitate to write us your questions and feedback which we will answer personally. Information We do our best to avoid bugs, often enough they drive us crazy or were disappointed when a moment was lost. But it has to come out sometime and after the update before the update. So feel free to write us bugs and problems, definitely also if you made a song or video. Soniface needs access to the camera for motion tracking, the microphone for audio recording, the local files to save projects and recordings, and the network for Ableton Link. Much more content, terms of use, credits and FAQ are in the app's guide and can be found in the app's start-up menu. About Mazetools Empowering creativity, democratizing musical expression and making it inclusive - how does that work? These are the questions that keep us busy. Soniface is a first step in the process and provides important points of contact through the multitouch-based principle & motion tracking input. But we want to go further - with you and the community. We wish you a great time with Soniface Pro, Stephan & Jakob

Features
Read full description

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. Classic Delay, Reinvented Quantum Delay takes the charm of a vintage stereo delay and fuses it with our next-level modulation system. Switch between the warm character of Tape mode and the pristine clarity of Fade mode, lock to BPM (including 5-tuplets) or dial in precise times in milliseconds. Use the Fine control for subtle push-and-pull micro-timing — or modulate your delay lines in ways traditional delays could only dream of. Sculpted Echoes Shape your repeats with switchable lowpass, highpass, and bandpass filters placed directly in the feedback path. Add modulation to create evolving tones, gentle movement, or drifting, frequency-shifting echoes. From warm analog-style rolls to shimmering, swirling textures, it’s all there. Feedback with Precision Control your delay tail behavior using either traditional % feedback or our modern dB-per-second decay system — ideal for predictable, musical decay even when the feedback path becomes complex. Enable Crossfeed for classic ping-pong stereo bounce, or push into Over-Feedback to create dense, self-building echoes that drift toward infinity. Stereo or Dual Mono Every section of Quantum Delay — delay, filter, and feedback — can switch between stereo and dual mono modes. Create tight, controlled stereo images or break them apart for wide, offset, unpredictable spaces. Dual mono modulation unlocks complex stereo interplay and beautifully asymmetric echoes. Modulation Without Limits Quantum Delay integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, stereo controls, and more. Use LFOs, Random Generators, 2D modulators, Envelope Followers, Macros, and even chaotic systems to push your echoes far beyond traditional delay behavior. Or use our parameter randomisation feature to explore the plugin’s sound at random. Quantum Delay is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX). More information here: https://gs-dsp.com/products
