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

Introducing ChaosArp, the next-level MIDI arpeggiator/step sequencer designed to transform your musical ideas into intricate, dynamic patterns with a unique twist. ChaosArp is not just any arpeggiator; it's a powerhouse tool that uses the same advanced algorithms as LoAdKer to modulate pitch, rhythm, velocity, and duration, creating evolving, complex but high musical patterns that breathe life into your music. Dive into the heart of your creativity with ChaosArp's innovative ‘rhythm event’ feature, which allows you to explore a variety of rhythmic modifications. From repeaters to stretchers and rests for extra space and emphasis—ChaosArp has it all. Each one of these rhythm events can be assigned to any of the 6 available slots, offering limitless possibilities. Fine-tune your sonic exploration with the innovative ‘variance’ control - which goes one step beyond the simple ‘probability’ control that most arpeggiators have. Adjusting this setting for either pitch or rhythm (or both) will vary the character of the generated sequences, from fairly minimalistic to completely chaotic, thus opening up a world of endless variations. Elevate your music production today with ChaosArp and unleash patterns that inspire! Features: - Two modes: arpeggiator and stepper - 1-16 steps - Scale quantizer, never miss a note again! - Variable rate, from 1/128 to 4 beats - 3 arpeggiator modes (up, down, up/down) - 3 stepper modes (forward, backward, ping-pong) - 1 to 4 octaves range - Latch mode - Pitch randomizer with probability and variance control and random octave - Rhythm event selector with probability and variance control - 6 assignable rhythm event slots - 13 rhythm event algorithms, including repeaters, stretchers, and rests - Repeat, stretch, and repeat rest probability controls for further customization of the rhythm event algorithms - Randomizable velocity and duration with variable range - 4 performance buttons that temporarily override the probabilities of pitch, rhythm, velocity, and duration - Automatable parameters
