"This project is a fully analog electronic keyboard synthesizer similar to the type that were very popular in the 1970s. Our synthesizer has a VCO, ADSR, and equalizer just like a commercially available keyboard. The VCO synthesizes our audio waveform and can be switched between generating a square or triangle wave. The keyboard that controls our VCO has two octaves of keys, and we have an octave switch that shifts the signal up an octave giving us a total range of three octaves. The ADSR generates an envelope that then gets applied to the VCO output. This signal then goes through the equalizer which modifies the frequency response of our system. The output of the equalizer feeds an integrated amplifier that drives a speaker and makes the sweet analog tones of our synthesizer audible.
