Levy Lorenzo developed a MIDI device that uses the movement of hamsters to control sound parameters of a musical sequence. The measurements were then fed into a Markov chain process in order to provide an additional layer of abstraction. Each sound was controlled by two hamsters, one responsible for the rhythmic qualities and the other the note sequence.
Sonasphere is an audiovisual software application by Nao Tokui which provides the user with a 3D canvas onto which they can add objects. The objects can be sound samples, effects or mixers, and it is possible to connect these objects together to modify the sound. Parameters of the objects can be assigned to 3D coordinates for the 3D canvas, so a filter object can have the cutoff frequency assigned to the x axis, the resonance to the y. The distance between a connected sound object and filter object control the volume. In addition gravitational forces act between each of the objects to create a more dynamic and chaotic environment.
The Beatbox is a physical programmable drum machine and consists of 5 tappers. Each tapper allows the user to play a rhythm, and then it can re-play the rhythm until it is stopped, or a new rhythm is played. The tappers can then be placed on different materials and objects to create a custom drum kit.
Developed by James Patten and Ben Recht, the audiopad tracks the position of objects on a tabletop and converts the movement into sound. The display provides visual feedback for the performer and the audience. The system is based on an earlier device made by James Patten called SenseTable.
