Read full description

Strng is a string synthesiser inspired by the karplus-strong algorithm. The physical modelling starts with a short burst of noise that then guided by a tuned delay buffer and string tension filter, generates plucked string like sounds. No samples are used. Strng is 16 voice polyphonic and can be controlled with an in app 25 key chromatic keyboard or connect prefered midi controller through USB or Wifi. To further shape the sound two post effects are available, a ping-pong stereo delay and two channel resonant filter controlled by two LFOs. Connect to other apps through AudioBus, inter app audio or load in DAWs as AUv3. +++ String synthesis engine +++ 16 voice polyphonic +++ Audiobus, IAA and AUv3 +++ Core MIDI, bluetooth midi and limited MPE +++ 25 multitouch keyboard with aftertouch control +++ Factory presets, save and load your own settings, drag'n drop from files app +++ Aftertouch modulation for attack, sustain, bit crush, resonant filter and detune lfo +++ Stereo ping-pong delay +++ Two channel resonant low pass filter LFOs

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
