In my final project for Professor Hidaki Isoda’s informatics music class at Texas Tech University in 2022, I developed a device comprising 10 motors, an electronic board, Arduino Uno, MIDI controller, and a laptop. This innovative motorized mechanism, integrated into a grand piano, induces sympathetic vibrations on ten separately controlled strings using a PCB kit. The Arduino code, created in Arduino IDE 2.0.3, interprets serial messages into motor commands, executed by ten transistors. The Max 8 patch employs the serial object to relay MIDI messages from a connected laptop, enabling precise control over the Arduino board and producing distinct motor vibrations. Notably, this device played a pivotal role in my master’s thesis, specifically in the composition titled A Song Below Water.
