Introduction:

Hypersynth multibank cartridge "Hcard-750" is specially designed for expanding the memory of Roland D-50 synthesizer. D-50 voice memory is limited to 64 presets (1 bank), which could be upgraded to 128 presets by adding an external "M-256" memory card. "M-256" card is discontinued, rare, and expensive and It relies on a battery for data retention. These flaws make it not a good choice for D-50 lovers in the modern age. "Hcard-750" can be used as a drop-in replacement for Roland "M-256" card, it stores up to 64 banks without the worry of battery life and data loss.
