Depends on the polyphony of the synth......for example, a Roland Jupiter 6 has 6 pairs of oscillators dynamically assigned by an on board cpu that scans the keyboard. When a key is pressed, a free oscillator pair is given a control voltage that represents the value needed to create the pitch of the pressed key and an audio gate is opened to allow that oscillator pair to sound through the synth's audio bus.
