|Abstract||A major problem of the composition process involving music technology is the selection of the tools within the broader context of the ever-changing language of multimedia production. The focus of the talk will be on creative applications of the SMSTools and Pure Data in two specific works Searching your Synesthesia (2005) for flute, clarinet, cello, piano and live electronics and ODD (2006) for electroacoustic multi channel 5.1 Surround Piece. The talk will provide a brief view on how this open source software offers the user the possibility to experiment with a vast number of compositional techniques in very flexible programming environments. This view is based on the analysis of the research that has been carried out within the compositional course of action concerning several pieces. It is intended to share a particular framework for enabling interactions between specific tools for the creative process.
