I build two different Pure Data Patches for the course. One takes external audio signals through the contact-mic inputs on the little Audio-interface we build in the course. The other one generates sounds purely out of Pd[[Pure Data]] a dataflow programming environment, no external sources used here. The first one i want to document here is the one without external audio. It's called "Glitches&Harmonics". It has many different functions as described below and different ways of using it. Some usages can be seen in the example video of that patch. The second patch is called "Grainman" after the guy who actually made this patch, called it like this and shared it with the community. It is an granular sampler which is able to granularize audio input in real-time. I found this really interesting with the use of the contact microphones. So i plugged a contact microphone on a kalimba instrument and took the audio input into this patch. My work on this patch was just the making of a midi mapping for using it smoothly with controller and the add of some effects like reverb, delay and filters.
