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 Tyros3). Modern electronic organ cannot "imitate" the timbre of musical instruments. It uses the timbre of a real instrument.
