CINCO VARIACIONES DE CIRCUNSTANCIAS FONICAS Y UNA PAUSA
Órgano [Organ] is a large-scale and site-specific interactive installation of a talking machine resembling a musical church organ. Originally installed at the Laboratorio Arte Alameda (LAA)–a former 17th-century church in downtown Mexico City–the device features two inputs: a musical keyboard and a typewriter. Each time users move to another line by striking the carriage-return lever on the typewriter, the words that have been typed are played back by means of a voice synthesizer. The musical keyboard, on the other hand, features a more complex system in which each key, music interval, and chord has been programmed to sound a specific syllable, comprising more than 2,000 syllables that make up the Spanish language. The latter programming has been translated into English, and more recently into Russian, for international exhibitions.

At last I am free
The Duo Goebbels/Harth (1975–1988), combining German composer, music-theatre director and keyboardist Heiner Goebbels and German composer, multi-media artist and saxophonist Alfred 23 Harth became famous for its adaptation of and departure from European composers, especially Hanns Eisler, implemented in a provocatively fresh manner into structured free improvisations and deploying content from areas beyond music. The duo was nicknamed the “Eisler brothers” by music critic W.Liefland. They later also experimented with different genres and sound collages, including electronic devices. The duo played in many international festivals and concerts in cities as diverse as Tel Aviv, Zagreb, West and East Berlin and South America.

Fly Tweet
This device sends twitter messages based on the activities of a collection of houseflies. The flies live inside an acrylic sphere along with a computer keyboard. As the flies move and interact inside their home, they fly over the keys on the keyboard. These movements are collected in real-time via video. When a particular key is triggered by the flies, the key’s corresponding character is entered into a twitter text box. When 140 characters are reached or the flies trigger the “enter” key, the message containing the accumulated characters is tweeted.

Clavilux
Clavilux 2000 is a subtle music visualization installation that represents the playing of sounds by way of a simultaneous animation that can be interpreted. For every note played on the keyboard, a stripe appears of which the dimensions, position and color correspond to the way the particular key was stroke.

Martela
FILE FESTIVAL
Tactila is an art form whose medium is the sense of touch (tact) which is independent from the all the other ones and has its own intelligence, imagination, memory, perception, and sensation. It is well known that vision and sound have hegemony in arts and in other disciplines. Tactila takes place in time and, therefore, can be recorded and have various forms of notation for subsequent executions. That is why its development became possible only now, thanks to mechatronic and robotic systems which are compatible with machine languages.
The creation of tactile works involves a (tact) composition, which can be made through handmade notation and played on a keyboard or directly on the computer of the tactile machine ( robot ).
Tactile machines can present numerous tactile possibilities through points, vectors, and textures with varying rhythms and intensities, and be run in different extensions and locations of our body.

.

The first tactile machine is called “Martela”. It is a tactile robot comprised of 27 engines subdivided into three squares (3 x 3), i.e., each square has 9 engines. Each engine corresponds to a matrix point, so we have 27 tactile units that allow to touch the user’s body with various intensities.

Shapeshifter Heartbreaker

Shapeshifter, Heartbreaker, is an installation on two levels composed of sculptural work and 3D computer animations that are both abstract and figurative. On the first level Pakui Hardware has designed an office desk using the typical components of a trading floor. However, this is not a work station for individuals; it is for computer aided trading, non-human activities which are approximated in the three channel videos atop desks noticeably lacking keyboards and mice. These activities often occur at an exceedingly fast pace, in the blink of an eye, an expression that lends its name to a video installed on the second floor. There, the blinks of a humanoid form have been accelerated to illustrate how fast the body would have to consciously react if it were operating at the speed of decision making that resulted in the stock market’s ‘flash crash’ of 2010.

vinyl+ • Expanded Timecode Vinyl
FILE FESTIVAL

A processing sketch is used to generate virtual objects being projected on white timecode-vinyl. These objects can either be placed randomly or by the user via the computer keyboard or an external midi controller. If the record starts to turn, the virtual objects will move with the speed of the record. If a virtual object touches the turntables needle, it will trigger an animation and the playback of a sound. This is possible because the vinyl’s timecode provides information about the record’s playback speed and the position of the needle, thus enabling to synchronize the movement of the turntable with the movement of the projection and to calculate collisions of virtual objects with the turntable’s needle. In vinyl+, an analog medium at the same time acts as a carrier and an interface for virtual audio- and video-objects.

the keyboard of isolation

keyboard study

The score to “Keyboard Study 1” is spare: two pages of musical cells and two pages of written instructions for how to navigate and manipulate those cells provide the pitch material, but choices about duration, dynamics, and shape are left up to the performer. There are three ostinati that form the skeleton of the piece between which are related sets of variations that will be mixed, matched, and sometimes played on top of the primary pattern. Riley offers the recipe for how to mix the ostinati and variation sets then its up to the performer(s) to choose which variation to use out of a particular set and how to shape the transitions from one ostinato to the next. Riley’s music empowers performers to create and react while also bonding their expression to the act of composition.
