Compositionally meaningful sound objects are subjected to a temporal change – spectral variation, which results as a pattern of change, as an invisible structure establishing the form of the sonic identity. We think the smallest sonic element as the granular sound event and its micro level characteristics influence the properties of the macro form. Our goal is to provide software based solutions controlled with compositionally meaningful parameters to drive this process of change . “… In fact it is not a sound that is produced, but a whole music in macroscopic form. This form is the result of rhythmic transformations, giving a polyrhythm of events with variable timbre, changing pitches and intensities – in short, rhythmic strands of meeting and jostling sounds…” (Xenakis 1985)
The overall goal of these software applications is to achieve a passage between the timbral attributes and the formal characteristics of the sound object which is created with the organization of micro sonic elements on multiple levels. Namely John Cage has regarded the form, the structure (the divisibility of a whole into parts) as the expressive content, the morphology of the continuity. The simultaneous morphologies in different dimensions, which focus on particular perceptual attributes of sound, lead to the existence of form.
No composition tool becomes reality by pure instinction, but with strong philosophical background. According to the existing valid compositional practices and further innovative extensions made on these valuable experiences, three software has been developed and been made available for you here;
Cosmosƒ, Stochos and Cosmos
While similar existing software tools do focus in exploring the possibilities of controlling the granular streams, we present algorithmic approaches with the help of mathematical methods not just to handle granular stream of sound events but also to explore new ways sonic organization within multiple layers and complexity .
Important Stochos and Cosmos applications are programmed on MaxMSP OSX platform (® Cycling74) and are no longer in development.
Cosmosƒ is developed in C++ and will be continuously updated (currently available for OSX and Windows7).
