The Wreckord Player is a project built with the modular-muse Pd library and runs on Raspberry Pi to make it a standalone project. The Pi fits nicely inside this old record player that came from my daughters pre-school. The Pd code for this uses granular synthesis techniques to record the audio from the record player and manipulate the sound in real time using the knobs on the front of the player. The knobs have been rewired to get the data to the Pi and Pd via an Arduino.
