This is bitHarp, a class-compliant, bit-crushable MIDI harp. It uses the Teensy ++ 2.0 microcontroller and is programmed in Arduino and MAX MSP. The harp was constructed with minimal materials and questionable woodworking skills, with strings made of the copper ground shield from a broken 1/4″ cable. The Arduino code has the Teensy sensing capacitance on the strings, and sends a MIDI note every time a string is touched. The sounds are synthesized in MAX, with the core being a gen~ Karplus Strong algorithm patch. I’ve also attached a Line 6 expression pedal that controls bit crushing. Comment with any questions or for MAX patches/arduino code!
