NotesThe Yamaha DX1 is the top-level member of Yamaha's prolific DX series of FM synthesizers. It featured two sets of the same synthesizer chipset used in the DX7, allowing either double the polyphony, split of two voices or dual (layered) instrument voices. In addition, it contained twice the amount of voice memory as the DX7, resp. it has an independent voice bank for each of two synth channels (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. It included a handmade Brazilian rosewood case, a 73-key weighted wooden keyboard with polyphonic aftertouch, comprehensive backlit LCD displays for instrument programming, and solid push-buttons as opposed to the membrane buttons on the DX7. There were only 140 of them ever made.
