Arduino String Synthesizer
Designed by Jan Ostman
Built and modified by Jet Kye Chong
Guidance from Gary Jörg White
In 2019, I salvaged an old, broken Yamaha keyboard from a trash heap. I took it a part to see what could be salvaged, including a 4-octave keybed. In the last week, I turned it into this synth.

Jan's design had controls for Envelope, Ensemble and Modulation only, for a 3-octave keyboard. My modification was to add a volume control (50k log potentiometer) and passive low pass filter (10k linear potentiometer + fixed 1k as specified by Jan), and adapt the code for a 4 octave keyboard with a different diode matrix shape.
First two demos use a delay pedal. First pedal uses a loop pedal.
