This summer I’ve been working on a prototype for a low-cost, Raspberry Pi synthesizer that is completely self-contained and ready for performance. The prototype uses a Raspberry Pi B+ computer and the built-in GPIO pins to provide controller inputs. No external micro-controller is necessary. Pure Data is the software engine behind the instrument which provides a never ending array of sonic possibilities. The goal of the project is to provide an updated instrument for my own performances and to provide an update to the system I’ve been using in my Networked Music Performance class at CalArts. For now I’ve been focussing on creating an audio synthesizer but a video synthesizer that uses the same hardware is also in the works. One goal for the project is to basically create a hardware “shell” that can be flashed with different software configurations for audio (Pure Data) and video (Python, PiCamera). The hardware, 16 buttons, 8 knobs and 8 sliders, will be installed in a custom case that will house the Raspberry Pi, provide a stereo audio connector and access to the USB ports for WiFi connectivity and battery operation possibilities.
