welcome, you are just visiting webpage where you can find "results" of "artistic research" done by michal cáb , . years ago i was mainly "composing" music and than i shifted more to the problematic of musical/visual instrument itself (probably under influence of kim cascone ) and its interface. guess interface hides an apriori for using which is kind problematic. these topics occupied my mind during ph.d. studies at academy of fine arts in prague ,.
pure data  has become one of convenient programming language for me. after few years of learning i figured out how to create simple music instrument and how to play it (which is something completely different than building it). later on i shortly explored another languages as supercollider  and some other weird stuff , .
i am usually having (noisy) concerts with my DIY built instruments (hw/sw) or cooperate with another musicians/visual artists. time by time i compose music for theatre  or create a specific sound designs. for last few months i am trying to shift myself again to more phenomenologic/ontologic thinking about sound. what is the sound? (well, hope this questions is enough till the end of my life).
importance of using open-source software in pedagogical/artistic processes is essential for me. so i am also trying to apply it in my pedagogical/artistic practices.
