VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. For more features including presets and unlimited recording see VOSIS Pro.

U-Lang is a visual sound instrument that can be used to create digital sound scapes on touch based devices. Its important aspects are the reduced set of grammar, a limited set of input methods. The goal is to create complex processes using very simple, yet very precisely controllable operations. The purpose of the application is to make the nature of sounds, scales and melodies accessible to both novices and experts in a unique way. Apart from musical concepts, U-Lang has a unique gestural interface that changes the way we interact with time & rhythm.
