Szymon Kaliski a mis en place un Raspberry Pi, des boutons et des potentiomètres et de nombreux circuits pour construire un boucleur audio à quatre pistes. Vous pouvez enregistrer quatre boucles de huit secondes, puis ajuster leur lecture à l’aide des boutons et des potentiomètres pour obtenir le son souhaité. Tout est très technique, mais il a écrit ce qu’il pouvait et l’a placé ainsi que le code sur Github. Voyez-le en action ci-dessous:
