Dataflow programming can be easier and faster to grasp than code based languages. We will focus on free, open source, and cross-platform Pure Data (Pd) visual programming language. Its native Open Sound Control (OSC) protocol will help us to get data from networking sound synthesizers, computers, and other multimedia devices. In small assignments we will gradually learn to use the software and solve tasks enabling us to realize more complex projects. Final results may be playful musical instruments, interactive installations or mobile apps which all together may be connected into an experimental orchestra. This class is aimed at a beginner level introducing Dataflow programming paradigms to artists and designers.
