Introduction:

Hypersynth multibank cartridge "Hcard-702" is specially designed for expanding the memory of the Yamaha DX7II synthesizer. DX7II voice memory is limited to 64 presets (1 bank), which could be upgraded to 128 presets by adding an external Yamaha "RAM4" cartridge. "RAM4" is discontinued, rare, and expensive and It relies on a battery for data retention. These flaws make it not a good choice for DX lovers in the modern age. "Hcard-702" can be used as a drop-in replacement for Yamaha "RAM4" cartridge, it stores up to 100 banks without the worry of battery life and data loss.
