16x banks of M256E / M256D card for Roland instruments.
Compatible with JV / JD / D series : JD-800, JD-990, JV-880, JV-1000, JV-1080, JV-2080, D70, D50, D550, D5, D20, D10, D110

***Important Note for D50/D550

This card is now updated to work with older Roland instruments, such as the earliest D-50 from 1987-1988. I have done limited testing and it's working well, but I also need feedback from other testers. If you are hesitant, please wait until more extensive testing have been completed.


16 position rotary knob on the card, allowing 16x times M256 card capacity.
Each switch position represents the entire memory available on a M256 card.
You can switch banks while the card is inserted in your Roland instrument.
Sale is for one 16x bank card as shown.

All cards are tested in my JV2080 before shipping. You will need to format each bank of the card with your instrument before use.
The back side of the card has arrow mark, to correspond with the arrow illustration on your Roland device (card being inserted into a JV2080 example picture shown for your reference). When correctly inserted, the LED (in classic Roland amber color) will light up as shown. If the LED is not lit up, that means you have either inserted it back-to-front or not fully in (in which case pull out and re-insert).
