The Yamaha DX1 is the top-level member of Yamaha's prolific DX series of FM synthesizers. The DX1 has two sets of the synthesizer chipset used in the DX7, allowing either double the polyphony, split of two voices, or dual (layered) instrument voices. It also has double the voice memory of the DX7. It has an independent voice bank for each of two synthesizer channels ("sound engines"). Each of 64 performance combinations can be assigned a single voice number, or a combination of two voice numbers - one from channel A and one from channel B.
