 ===== Introduction =====
 ProtoTone Synth is a musical instrument based on the widely popular Stylophone. You can play musical notes by touching the copper pads with a stylus and manipulate them in real time.

-Based on the key pressed, the microcontroller will output a different musical note and it will be shown on the display. The musical note can be pitched up or down using the joystick, which is just a potentiometer that returns to the neutral position. With the twisting of the Modulation potentiometer, the note will begin to jitter consistenly based on the level set. The volume will also be able to be adjusted by twisting yet another potentiometer. At the end, we are left with the actions of the 4 buttons. Two are for choosing the octave, going both ways. Another is for holding the current note, letting you lift the stylus off the key and it would still play, and the last one is for cycling through waveforms. You can choose between square, saw and triangle.

You can choose between square, saw and triangle.
 The display will output the current note playing, the current octave for a short period of time when changing it in any way, and the current waveform when cycling.
