The development of the new CP series started with the no-compromise CP1. This is a premium instrument with a commitment to both tradition and innovation. The core sound technology inside the new CP Series was completely re-designed from the ground up. A unique new Spectral Component Modeling tone generation system recreates the sound of acoustic and vintage electronic pianos more faithfully than anything else has ever done. This new technology responds to the player's touch allowing more creative expression than ever before possible. Yamaha even developed a special NW-STAGE wooden key action specifically to meet the demands of top pros. Simply put, this combination of touch and tone make the CP1 the most expressive stage piano that has ever been created.
