"ONE OF A KIND custom WHITE YAMAHA DX5 6-operator digital FM synthesizer.
This DX5 is not like any you are likely ever to have seen. It has been specially modified by Allen Coppock at Nashville's famous Synth Spa with a custom made white overlay, which retains the beautiful pastel colors that the factory DX5 uses, but how striking they look on a white background! It has special rosewood side panels and new negative display in place of the original---even the sharps and flats are not black but are that Yamaha brown that is the standard body color of the DX5 and DX7, and that matches the brown lettering on the control panel! In addition, the action has been gone over and the synth has been recapped. This DX5 also includes a pair of the amazing Hypersynth 705 cartridges. These alone cost $429.00 and are not even currently available, having been sold out.
Hypersynth 'Hcard-705' is a multibank cartridge pair for expanding the external memory of Yamaha DX5 and DX1. DX5/1 voice memory is limited to 32 presets for each parts A and B, which could be upgraded to 64 presets by adding an external Yamaha "Data RAM" cartridge. "Data RAM" is discontinued, rare, and expensive. Its third-party versions rely on a battery for data retention. "Hcard-705" can be used as a drop-in replacement for Yamaha "DATA RAM" cartridge. it stores up to 400 banks per cartridge without the worry of battery life and data loss. Hcard-705 is compatible with DX5/1 voice and performance format.

Hyper-Bank contains 64 presets in 8 categories: Gated/Rhythmic, Synth, Pad, Yamaha Bests, Key/Piano, Bell, Bass/Lead, Misc.
