Kits for the Akai MPC Sample are built as .xpj project files, one project per kit, with all of a pack’s kits together in one folder. Each .xpj has a matching _[ProjectData] folder, and the two have to stay side by side.

To get them onto the device, put a microSD card in the MPC Sample’s left slot, hold Shift and tap Pad 16, then choose SD Card Access to mount the card on your computer. Copy the kit folder to the card. The kits can go anywhere on the card, including the root.

After copying projects to the card, power the MPC Sample off and back on. New projects don’t appear until the device restarts. This works the same way in reverse: projects you save on the device won’t show up on your computer until after a restart either.

To load a kit, use Load Project, press the middle button to switch to External, and browse to the kit. Then press the Load Kit button. Don’t press down on the knob, because that opens the file as a full project, which replaces your whole session.

A kit loads as one kit of up to 8 banks, and loading it replaces every bank at once.

Preferences has a second file type, .mpcsample, if .xpj ever gives you trouble. See MPC Sample.
