Yamaha DX5


The DX5 is basically a budget version of the flagship DX1, and part of the first repackage of the FM technology after the initial line released in 1983.

Shown at the Frankfurt MusikMesse 1985, it gives the public the internals of the DX1 and all its 6op layering features at a fraction of the price (2.999£ instead of 7.000£) and weight (18kg instead of 51kg). Musicians who relied on two separated DX7 synths (1.300£ each) to achieve chorusing could now get a single package with the same sound capabilites and better memory management at a similar cost.

This is achieved by cutting on the interface, which maintains lots of buttons and the larger LCD screen but looses all the real-time visualization, and the use of a light plastic keyboard instead of weighted keys.
