This music synthesizer accepts user input via a keyboard using a PS/2 interface. The user has the ability to control two parameters: waveforms and octaves. Waveforms are generated by means of the direct digital synthesis algorithm. The user may select from six waveforms: sine, square, sawtooth, triangle, EKG, and sinc. The synthesizer covers the seven octaves present on an 88-key piano in addition to the two incomplete octaves for a total of nine octaves.
