Musical Artefects 2022

Musical Atrefects is a collection of audiovisual short stories where the movements of constructions formed by virtual objects are controlled by musical instruments. Each part is based on one polyphonic rhythm sequense of its own. All instrument sounds except the acoustic guitar are produced electronically and generated from this sequense utilizing weighted randomness in the selection of density, velocity and pitch of the notes.

Software used:
Ableton Live / Max for Live

Formal Music 2020

Formal Music is a six part series of audiovisual compositions for guitar, two sensor instruments and an interactive virtual combo. The compositions are based on the development process of centralized real-time control of virtual electronic instruments. It is a solo work that includes visual elements that are composed to respond to every note of every instrument. The form, movement, size, texture, color and brightness are following the values of the MIDI data produced by the instruments.

Ornaments installation . Improvisation Ornaments Part6. Flash 2017 Suomenlinna. All three sensor instruments in use. Leap motion trackers are used to control individual instruments as well as the intensity and probability of the background materials. Every note is being visualized with programmed animations on 3D screens based on origami folding techniques.


Visual Music Orchestra process. Improvising with real time controlled musical accompanying elements (rhythm, harmony, bass line) and synchronized visual elements (animated objects). Control data is used also for intensity changes, density, color and sustain of notes and changing size, luminosity, movements and blurring of the visual objects.
