Read full description

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.

Wilsonic is your portal to new musical universes. Ervin Wilson's 65 years of tuning research and discovery are now at your fingertips.

No previous knowledge of music theory is required. These tonal worlds are based on an entirely unique mode of thought that has little to do with historical musical thinking. The app features Wilson's most profound scale designs. Your hands and ears naturally find new melodic patterns and harmonies that touch on those feelings and emotions you couldn't find before.
