The function of an oscillator is to generate an oscillation signal with a certain frequency as required. The oscillating signal is decomposed into signals with different frequencies by the frequency divider and sent to the amplifier, which amplifies the signal and drives the speaker to make sound.

Working principle:
Modern electronic organ generally adopts PCM sampling sound source. The so-called sampling is to record the sound of an instrument, digitize it and store it in ROM or FLASH, and then play back the sound when pressing the key. There are even some advanced arranger keyboards that can use external sampling (such as the hard disk timbre of Tyros 3).
Modern electronic organ cannot "imitate" the timbre of musical instruments. It uses the timbre of a real instrument. Of course, the sense of force in the electronic organ is essential. Modern waveform memory electronic organ also has filters and oscillators, and can also make and edit timbre through envelope control.
