This project is a MIDI / piezoelectric piano implementation. It utilizes 12 buttons and 2 rotary encoders to give a full octave worth of piano keys, with the ability to jump up or down the keyboard by either a full octave or individual notes depending on the encoder used. Using 3 piezoelectric buzzers, it also has the capability to play chords.
The piano part of it is fully functional. The buzzers work well and so do the encoders.
While the MIDI is fully implemented and tested, it hasn't been verified so it may not be sending the time signals perfectly.
