The 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 or dual simultaneous instrument patches. In addition, it contained twice the amount of patch memory as the DX7. It included a handmade Brazilian rosewood case, a 73-key weighted wooden keyboard, 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. [1]
The Yamaha DX5 was a derivative of the DX1. It lacked the DX1's aesthetics and cross FM functions, but included 76 keys with channel aftertouch and slightly improved MIDI features.
Programming instruments on the DX1 is more advanced than a DX5 where on the DX7 the programming is less complex.
