FM is Yamaha's proven Frequency Modulation synthesis technology that is capable of creating extraordinarily warm, vibrant simulations of actual instruments, as well as an infinite variety of orginal sounds. The vector synthesis system brings these two tone generation systems together. View full synthesizer Share this post Link to post Share on other sites
