It's a clone of the original Roland M-64C, but with double the memory capacity and made from new components. Comes with a professionally 3D-printed casing and waterproof label.

The cartridge is made by me, designed and assembled by hand to order in Taiwan with all new PCB and components. It is perfect for those who are looking for a replacement or an additional memory cartridge. With this memory cartridge, you can ensure that you have enough storage space for your vintage instruments. It features two switchable memory banks, basically equal to two Roland M-64C cartridges.
