This is a CF card that can be used with AKAI MPC 500, 1000, 2500, etc. It contains original AKAI sound data. I did some research online, and it seems difficult to obtain this card new or used at present. It may be a valuable item, so please consider purchasing it if you are interested. I work on weekdays, so there may be delays in communication and shipping. Thank you for your understanding. Please contact me if you have any questions.
