Oscillators (an introduction to)

The Oscillator (VCO) is the part of the synthesizer that generates the initial tones that are shaped (envelope) to form sounds as desired.. the number of oscillators, the type of wave they are generating, combined with the way in which the tones are combined determines the type of sound that is produced.

It is the most important module in the synthesizer as the final sound produced is primarily determined by the way you set up your oscillators. The common controls found on your oscillator are:
Wave Type -Simple waveforms (wave/sine/saw/tri/square), complex waveforms (pulse, noise etc).
Octave Select - Primarily used to fatten up sounds.
Semitone Select - Useful for creating small chords, especially on monophonic synthesizers.
Detune Pitch - Useful for creating more realistic sounds.
