The P-525 features improved organ, electric piano, and other keyed instrument Voices. The engineers who achieved these improvements are experts in the sound of electric organs and electric pianos and the musical culture associated with them. Their efforts to create faithful, high-quality simulations of familiar sounds—the attack of an organ and the distinctive sound of its Leslie speakers, the reverb, distortion, and other sound effects of the electric pianos that defined 70s and 80s pop music—result in realistic, immersive experiences that make you feel like you are actually playing those instruments.
