Introduction:

Hypersynth multibank cartridge "Hcard-701" is specially designed for expanding the memory of the Yamaha DX7 synthesizer. DX7 voice memory is limited to 32 presets (1 bank), 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. These flaws make it not a good choice for DX lovers in the modern age. "Hcard-701" can be used as a drop-in replacement for Yamaha "DATA RAM" cartridge. it stores up to 400 banks without the worry of battery life and data loss.
