This is the PCMCIA Nord Sound Memory card for the Nord Lead synth. It is battery backed and holds 297 single sounds and 100 performances. Card is used but in great shape. There have been several unique sounds/performances programmed and stored on this card but they can be saved over if not to your liking. Card has been tested and is working as expected. I have 100% positive feedback and pack shipments carefully so you can buy with confidence!
