This pre-assembled add-on allows you to use Standard Density Micro-SD cards (less than 2GB, the ones that cost a dollar on eBay) to permanently store audio samples and it allows you to transfer samples between WTPA2 and a computer using the free sample packer/extraction software. It also adds the capability to play Nintendo Entertainment System DPCM formatted samples like a variable-pitch drum machine.
