“Relive the fun of early computer game music with an authentic 8-bit chiptune synthesizer, which you can control over MIDI from the comfort of any modern DAW software.
This simple circuit uses an Arduino to drive an AY-3-8910 programmable sound generator chip (or one of its many clones) to recreate that 1980’s sound. Unlike the many designs that need specialised software to edit music, this looks like a standard USB MIDI device. The synthesizer has a clever algorithm which tries to keep the most musically-relevant notes playing; in many cases you can throw un-edited MIDI files straight at it and the tune comes right out. Total cost should be about 20.”
