This paper describes the audio human computer interface experiments of ixi in the past and outlines the current platform for future research. ixi software [5] was founded by Thor Magnusson and Enrike Hurtado Mendieta in year 2000 and since then we've been working on building prototypes in the form of screen-based graphical user interfaces for musical performance, researching human computer interaction in the field of music and creating environments which other people can use to do similar work and for us to use in our workshops. Our initial starting point was that computer music software and the way their interfaces are built need not necessarily be limited to copying the acoustic musical instruments and studio technology that we already have, but additionally we can create unique languages and work processes for the virtual world. The computer is a vast creative space with specific qualities that can and should be explored. Keywords Graphical user interfaces, abstract graphical ...
