"The MPC1000 inherits all of the essential MPC features such as 32-voice stereo sampling, 64-track sequencing, and 16 velocity and pressure-sensitive MPC pads, fitting all the production capability into a compact, affordable package. 16MB of on-board memory comes standard and can be expanded up to 128MB. You can save your work to a Standard Compact Flash Card (up to 2GB).
When connected to a Mac or PC via its built-in USB port, you can simply drag and drop data between the computer and MPC1000's CF card. MPC1000 is small, rugged and incredibly portable for an easy fit into a backpack or laptop bag for the traveling producer."
