In their new flagship keyboard, the MONTAGE, Yamaha debuts the Motion Control Synthesis Engine, which combines and controls two iconic sound engines: AWM2 (high-quality waveform and subtractive synthesis) and FM-X (modern, pure Frequency Modulation synthesis.) These two engines can be freely zoned or layered across eight parts in a single MONTAGE Performance. The Motion Control Synthesis Engine is a programmable control matrix for creating deep, dynamic and expressive sound. With Motion Control, you can create new sounds that were not possible on previous hardware synthesizers. It is truly a new world of synthesis.. This product comes with a case.
