![]() ![]() The unhappy inventor is taught, by his failure, that it is as Important invention is made before the world is ready to receive it, and Hence, the same invention is frequently brought out in severalĬountries, and by several individuals, simultaneously. Is not a creation but a growth - as truly so as that of the trees in theįorest. Every great invention is really either anĪggregation of minor inventions, or the final step of a progression. The Problems of Exploding Boilers Great inventions are never, and great discoveries are seldom, the In particular, parallels existīetween the early development of high-pressure steam engines and softwareĮngineering that we can apply to the use of computers in complex systems. Useful new technology that is potentially dangerous. This is not the first time that humans have come up with an extremely Risk induced by technological innovation existed long before computers Possible and at a speed that does not expose people to undue risk. Introduced into safety-critical systems in the most responsible way Technological benefits of using computers become more widely accepted, The number of computer-related accidents soįar has been small due to the restraint that has been shown in introducing The introduction of computers into the control of potentially dangerousĭevices has led to a growing awareness of the possible contribution of Science is only orderly after theįact in process, and especially at the advancing edge of some field, it Rational order, we should not infer from that order that the genesis of Seattle, WA 98195 Even though a scientific explanation may appear to be a model of This paper was presented as a keynote talk at the InternationalĬonference on Software Engineering, Melbourne, Australia, May 1992 and is It was made possible thanks to a partnership between the Centre Iannis Xenakis and the European University of Cyprus, with funding from the Interfaces Project.A shortened version of this paper appeared in IEEE Computer, October 1994. The first version, released in 2018, runs on OSX and iOS. ![]() For its part, HighC is currently used as a pedagogical tool in classes ranging from early teens to Master classes in composition, while some contemporary composers, such as George Hatzimichelakis have made it part of their toolset.Īnother pedagogical tool, UPISketch, was inspired by the UPIC. IanniX, which has been sponsored by the French Ministry of Culture, is a graphical open-source sequencer which syncs via Open Sound Control events and curves to a real-time environment (like Pure Data, SuperCollider, Csound, MaxMSP and openFrameworks among others). There were a couple of attempts to reproduce the UPIC system using commodity hardware, for instance Iannix, HighC, UPISketch. In 2005, Mode Records of New York released a 2-CD compilation of works composed with the UPIC at CCMIX, entitled Xenakis, UPIC, Continuum, which provides an overview of the machine's sonic possibilities. The UPIC system has subsequently been expanded to allow for digitally sampled waveforms as source material, rather than purely synthesised tones. The system allows for real time performance by moving the stylus across the tablet. They can also be transposed, reversed, inverted, and subject to a number of algorithmic transformations. The compositions can be stretched in duration from a few seconds to an hour. Once the waveforms have been stored, the user can compose with them by drawing "compositions" on the tablet, with the X-axis representing time, and the Y-axis representing pitch. Its functionality is similar to that of the later Fairlight CMI, in that the user draws waveforms and volume envelopes on the tablet, which are rendered by the computer. Physically, the UPIC is a digitising tablet linked to a computer, which has a vector display. ![]() Aphex Twin implies that he uses UPIC in an interview where he is asked what software he uses and he replies that, "UPIC by Xenakis puts almost everything else to shame it's under 1mb". It has also been used by composers such as Julio Estrada, ( Eua´on (1980)), Jean-Claude Risset (on Saxatile (1992)), Jorge Antunes ( Interlude de l'opéra Olga (1992)), François-Bernard Mâche ( Hypérion (1981), Nocturne (1981), Tithon (1989), Moires (1994), Canopée (2003)), Takehito Shimazu ( Illusions in Desolate Fields (1994)), Gérard Pape ( Le Fleuve du Désir III (1994)), and Curtis Roads ( Purity (1994) and Sonal Atoms (1998)). Xenakis used it on his subsequent piece Mycènes Alpha (1978) and two other works. It was developed at the Centre d'Etudes de Mathématique et Automatique Musicales ( CEMAMu) in Paris, and was completed in 1977. UPIC (Unité Polyagogique Informatique CEMAMu) is a computerised musical composition tool, devised by the composer Iannis Xenakis. For other uses, see UPIC (disambiguation). ![]()
